A convex mirror forms only virtual, diminished and erect images for all positions of the object, whereas a convex lens can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object.
What is difference between glass and lens?
Comparison chart A contact lens is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. Glasses or spectacles are frames bearing lenses worn in front of the eyes, normally for vision correction, eye protection, or for protection from UV rays.
What is the difference between mirrors and lenses in terms of the manufacturer?
Mirrors are made of glass and metal. Lenses are made of glass and plastic. 7. Concave mirrors are converging, whereas convex mirrors are diverging.
What are the 3 main differences between a convex and concave mirror?
(1) In a convex mirror, the inner surface of the sphere is a reflecting surface. (2) The radius of curvature of a concave mirror is negative. (2) The radius of curvature of a convex mirror is positive. (3) A concave mirror converges all the light rays at a single point.
What is the difference between reflection and mirror?
When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a "mirror image." People commonly think of the reflection as being reversed left to right; however, this is a misconception.
What is a lens Class 7?
A lens is a piece of transparent glass which concentrates or disperses light rays when passes through them by refraction.
What are the types of mirror and lenses?
Basic lenses and mirrors come in two different kinds: concave and convex. These types differ in how and where they focus light. A concave lens diverges light—scatters it and cannot bring it into focus—and the 'image' that it forms shows up on the same side as the light it is reflecting.
Are lenses and mirrors opposite?
SIGN CONVENTIONS: For a mirror or lens, the light rays come into the optical device from one side; let's call this the “IN” side. The light rays leave the mirror or lens on the “OUT” side. For a mirror, the “OUT” side is the same side as the “IN” side; for a lens, it's the opposite.
What is the difference between magnification formula of mirror and lens?
Lens: For lens, the linear magnification produced is the ratio of the image distance to the object distance. Mirror: For mirrors, the linear magnification produced is the ratio of the -image distance to the object distance.
What is mirror formula and lens class 10th?
Mirror formula is given as, 1f=1v+1u. Here, f is denoted for focal length which is the distance between pole and focus of a concave or convex mirror. v Is denoted for image distance which is measured from pole to the point where image of an object is formed.
Is magnification formula for lens and mirror same?

What is the difference between a mirror and a lens?
The points presented below are substantial so far as the difference between mirror and lens is concerned: 1 By the term ‘mirror’ we mean a shiny piece of glass, that is polished from the back, which reflects a clear image of the object, placed in front of it. On the other hand, Lens is a transparent piece of glass, with a spherical surface, that concentrates or disperses the rays of light falling on it. 2 A mirror is either plane or spherical. In contrast, a lens has two surfaces, at least one of which is curved inwards or outwards. 3 As the light ray strikes the mirror, it reflects off the light in a different direction, resulting in the formation of an image. Conversely, in case of lenses, the light ray enters the medium (lens), which refracts (bends) the rays in a different direction, creating a focus, from where the rays seem to originate. 4 To calculate the nature of images formed by a mirror and a lens, we use their equation, which is given as under:#N#Mirror Equation:#N#Lens Equation:#N#Where v = Distance of image from the pole.#N#u = Distance of object from the pole.#N#f = focal length of a spherical mirror
What is mirror lens?
In simple terms, mirror means a smooth and highly polished glass surface, through which images are formed by reflection, as the light falls on it. On the other extreme, a lens is a part of the transparent refracting medium, (i.e. glass), bounded by two surfaces, of which at least one is spherical. It helps in the formation ...
What is a plane mirror?
Plane mirror: A mirror with a flat surface is called a plane mirror. It produces virtual and erect images. Spherical mirror: A mirror that has a curved surface, which is used to form a diminished or magnified image, is called a spherical mirror. It is of two types convex and concave mirror, as described below: ...
Why do objects visible from a lens appear larger or smaller than the actual object?
The working of the lens is based on the principle of refraction, i.e. the light rays bend after they pass through the lens and thus their direction changes and that is why the objects visible from the lens seems larger or smaller than the actual object.
Which type of lens is curved outwards from the centre?
Convex Lens: The surface of a convex lens is curved outwards from the centre, which converges the rays of light. Binoculars and telescope, magnifier, etc. use this type of lens. Concave Lens: Concave lens has a surface that bulges inward towards the centre, and thus it diverges the light beam.
How many surfaces does a lens have?
In contrast, a lens has two surfaces, at least one of which is curved inwards or outwards. As the light ray strikes the mirror, it reflects off the light in a different direction, resulting in the formation of an image.

What is the sign convention of the lens?
Sign Convention of the Lens: All the distances should be measured from the optical center of the lens. Distances that are considered along with the direction of the incident rays should be considered positive, and negative when distances are taken from the opposite side of the incident rays.
What is a lens?
Lenses are devices which are used in optics and other related fields. Lenses manipulate light by using refraction. There are several types of mirrors. These are namely biconvex, Plano – convex, positive meniscus, negative meniscus, Plano – concave and biconcave. Lenses can be also classified into simple lenses and compound lenses. Lenses are used in applications such as telescopes, spectacles, contact lenses, cameras and various others. A perfect lens refracts all the light which incidents on it. Lenses are manufactured by grinding glass or clear plastics into desired shapes. The refraction from a mirror obeys Snell’s law.
What is the difference between a mirror and a lens?
A mirror is a device that is based on the principle of reflection whereas lenses are devices that are based on the principle of refraction. Both of these devices are very important in fields such as optics, astronomy, photography and various other fields. In this article, we are going to discuss what mirrors and lenses are, the working principles of mirrors and lenses, their applications, and the similarities and differences between mirrors and lenses.
What is a mirror?
A mirror is an object that reflects light falling on it. Mirrors are generally made from applying a reflective coating. The reflective coating is made up of several layers of different material. First a Tin (II) chloride layer is applied to bind the silver layer to the glass layer. Then a silver layer is applied on top of the Tin (II) chloride layer. On top of these two layers, a chemical activator layer is applied to harden the silver. A copper layer is added for durability, and the whole thing is coated with a paint layer to stop corrosion. There are two main types of mirrors. These are plane mirrors and curved mirrors. Curved mirrors fall into two classes known as concave mirrors and convex mirrors. A mirror operates on the principle of reflection. The principle of reflection for any surface is that the angle of incident and angle of reflection are equal. These angles are measured from the normal line drawn to the reflective surface on the point of incident. This line is also on the plane which contains the incident and the reflective beam.
What is the difference between a mirror and a lens?
The major difference between Mirror and Lens is that Mirrors reflect the light whereas the Lens Refract the light. Mirrors are objects that reflect the light falling on them and help us to see our image on them. Lenses are the ones that manipulate the light and form the image by refraction.
Why are mirrors polished?
