What is a mirror formula?

Define linear magnification produced by a mirror?

Find the height of the image of a body of height 1.5m in a mirror with a magnification of 1.5.

The boxes in figure (a, b, c) represent mirrors; insert a mirror which will reflect the incident ray as shown in the diagram.

What is the relationship between the focal length and radius of curvature?

AB is the object, A₁B₁ is its image. MM' is the position of the mirror. Complete the ray diagram and find the position of the center of curvature and focus of the mirror. Also, measure the focal length.

AB is the object, A'B_' is the image, and MM' is the position of the mirror. Complete the ray diagram showing the formation of the image and find the focal length of the mirror.

In the following figure shows a concave mirror with its pole (P), focus (F) and centre of curvature (C). Draw a ray diagram to show the formation of the image of an object AB by the concave mirror.

The following figure shows a concave mirror with its pole (P), focus (F), and center of curvature (C). Draw a ray diagram to show the formation of the image of an object AB by the concave mirror.

Complete the following diagrams shown in the below figure by drawing the reflected ray for each incident ray.

Complete the following diagrams shown in the following figures by drawing the reflected rays.

Define the term Pole.

Define the term Centre of curvature.
