How an image is formed in a mirror using a ray diagram?
The two rays, CY and DM are diverging rays and when extended behind the mirror, they appear to intersect each other at point M'. Therefore, the properties of the images formed here are formed behind the mirror, between the pole and principal focus (f), the images are diminished and are virtual and erect.

Which of the following ray diagrams is correct for the mirror shown?
The ray diagram in option D is correct. After reflection, a ray of light incident parallel to the principal axis passes through the focus in case of a concave mirror.
What is a ray diagram?
A ray diagram is a diagram that traces the path that light takes in order for a person to view a point on the image of an object. On the diagram, rays (lines with arrows) are drawn for the incident ray and the reflected ray.

How many ray diagrams are there for convex mirror?
In case of a convex mirror any of the following four ray diagrams can be used for locating the image formed: a) When the ray is parallel to the principal axis. After reflection, the rays appear to diverge from the principal focus of a convex mirror.
What is the formula for mirror?
Let's explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
Why do we use ray diagrams?
Ray diagrams can be particularly useful for determining and explaining why only a portion of the image of an object can be seen from a given location. The ray diagram at the right shows the lines of sight used by the eye in order to see a portion of the image in the mirror. Since the mirror is not long enough, the eye can only view ...
Why is the ray diagram shaded green?
As the eye tries to view even lower points on the image, there is not sufficient mirror present to reflect light from the lower points on the object to the eye. The portion of the object that cannot be seen in the mirror is shaded green in the diagram below. Similarly, ray diagrams are useful tools for determining and explaining what objects might ...
What is the lowest point on an image that the eye can see?
The lowest point on the image that the eye can see is that point in line with the line of sight that intersects the very bottom of the mirror.
What does the dashed line mean in a mirror?
It is customary to draw a bold line for the reflected ray (from the mirror to the eye) and a dashed line as an extension of this reflected ray; the dashed line extends behind the mirror to the location of the image point. The reflected ray should have an arrowhead upon it to indicate the direction that the light is traveling.
What is the line of sight principle?
The line of sight principle suggests that in order to view an image of an object in a mirror, a person must sight along a line at the image of the object. When sighting along such a line, light from the object reflects off the mirror according to the law of reflection and travels to the person's eye. This process was discussed and explained earlier ...
Why do you need an arrowhead for a reflected ray?
The reflected ray should have an arrowhead upon it to indicate the direction that the light is traveling. The arrowhead should be pointing towards the eye since the light is traveling from the mirror to the eye, thus enabling the eye to see the image. 3. Draw the incident ray for light traveling from the corresponding extreme on the object to ...
Which eye is Suzie viewing in the mirror?
Thus, we will focus on how light travels from the two extremities of the object arrow (the left and right side) to the mirror and finally to Suzie's right eye as she sights at the image.
Problem 1: choose the correct ray diagram
In this problem, we are dealing with a convex lens. Let’s draw three rays, all originating from the top of the object.
Problem 2: choose the correct ray diagram
Here we have another convex lens, but this time our object is outside of the lens’ focal point. Again, let’s draw three rays, each emanating from the top of the object.
Problem 3: choose the correct ray diagram
Now we have a concave lens, which diverges light to create a virtual image on the object side of the lens.
Problem 4: choose the correct ray diagram
Now we have a concave mirror, which can either create a virtual upright image or a real inverted image depending on the location of the object. In this problem, the object is within the focal distance, so the mirror will produce an upright virtual image on the opposite side of the mirror.
Problem 5: choose the correct ray diagram
Our final problem deals with a convex mirror. Convex mirrors diverge light, and they produce virtual upright images on the opposite side of the mirror.
How to Draw a Ray Diagram for an Object in Front of a Concave Mirror
Step 1: Draw two incident rays departing from the top of the object and reaching the mirror in different directions.
What is a Ray Diagram for an Object in Front of a Concave Mirror?
Concave mirror: It is a type of spherical mirror whose reflective side is located at the interior part of a spherical cap.
Examples of Ray Diagrams for Objects in Front of a Concave Mirror
Locate the image created from an object placed on the center of curvature of a concave mirror.
