The image formed by a plane mirror is virtual, erect, of the same size as the object and laterally inverted. The distance between image and mirror is equal to the distance between object and mirror. If two or more mirrors are kept close to each other, we can get multiple images of a single object, placed in between the two mirrors.
How is the position of image related to the position of the object class 9?
The image is as far behind the mirror as the object is in front of it i.e, the perpendicular distance of image from the mirror is equal to the perpendicular distance of object from the mirror.
How is position of the image related to the position of the object and the focal length of the mirror?
When the object is far away from the mirror the image is upright and located at the focal point. As the object approaches the mirror the image also approaches the mirror and grows until its height equals that of the object.
Is the image formed by a plane mirror exactly the same as an object?
Yes. Followings are the characteristics of image formed by plane mirror: It is virtual and erect and laterally inverted. Magnification is unity i.e. size of image is equal to size of object.
What will be the location of the image formed in a plane mirror?
behind the mirrorImages in a plane mirror are the same size as the object, are located behind the mirror, and are oriented in the same direction as the object (i.e., “upright”).
What happens to the position of the image as the object is brought nearer to the lens?
Clearly, moving the object closer to the lens makes the image become both larger and further away. As you move the object closer and closer to the focal point, the image will become further and further away.
How do you find the position of an image in physics class 10?
1 mm. 12 mm (focal length = 12 cm). 6 mm (distance of object = 6 cm). 24 mm....(i) Position of image.Here, Object distance, u=− 25 cm (To the left of mirror)And, Focal length, f=− 20 cm (It is concave mirror)9 more rows
What are the characteristics of the image formed by a plane mirror Class 7?
Characteristics of image formed by a plane mirror are: The image formed is virtual. The image is laterally inverted. It is of the same size as the object. The image is erect. Distance of image from the mirror will be the same as the distance of the object from the mirror..
How are images formed in a plane mirror Class 8?
A plane mirror always forms a virtual image, i.e., the rays of light from the object don't actually form the image; but these are the extensions of the reflected light rays that appear to intersect behind the mirror. Hence, the image is formed on the reflecting surface.
Why is the image formed by a plane mirror the same size?
The image formed by a plane mirror is of the same size as that of the object and is formed at the same distance behind the mirror as the object is in front of the mirror and the image formed is virtual, erect, and laterally inverted.
What are the properties of image formed by a plane mirror?
Properties of an image formed by plane mirrorThe image obtained is virtual.The image is laterally inverted.The image is erect.The size of the image is the same as the size of the object.The distance between the image obtained from the mirror is the same as the distance between the object from the mirror.
What are the characteristics of image formed by a plane mirror?
Characteristics of the image formed by a plane mirror are:Virtual and erect.Behind the mirror.Size of the image is equal to the size of the object.Laterally inverted image. ( ... Distance of the image behind the mirror is equal to the distance of an object in front of the mirror.
How does the law of reflection show how an image formed in a plane mirror?
When the light rays get stroked on the flat mirror, they get reflected back. According to the laws of reflection, the angle of reflection is equal to the angle of incidence. The image is obtained behind the plane, which is present in the mirror.
How is the position of image related to the position?
Q17) How is the position of image formed by a plane mirror related to the position of the object ? Answer: Solution : The image formed by a plane mirror is laterally inverted, upright, of the same size and is formed far behind the mirror as the object is in front of it.
What is the relation between object distance image distance and focal length?
Hence, the relationship between object distance, image distance, and focal length of a spherical mirror is 1 v + 1 u = 1 f .
What is the position of the image when an object is placed?
Solution. When an object is placed at a distance of 20 cm from a concave mirror of focal length 20 cm, the position of the image is at infinity. The reason being, the image formed by a concave mirror is at infinity when an object is placed at its focus.
How do you determine the position of an image of a lens?
To determine the position of the image, two equations are generally used: The Newtonian Image Equation describes the position of the bject and the image relative to the focal points of the lens. The Gauss-equation describes the positions of the object and the image relative to the principal points.
