Explain the following terms :
Pole, Centre of curvature, Radius of curvature, Principal axis. Show them on separate diagrams for each of the concave and convex mirrors.
How is a spherical mirror used to diverge a beam of light from a point? Name the type of mirror used.
Upto what maximum distance from a concave mirror, the image can be obtained? What will be the location of object for it?
A point light source is kept in front of a convex mirror at a distance of 40 cm. The focal length of the mirror is 40 cm. Find the position of image.
An object forms a virtual image which is 1/8th of the size of the object. If the object is placed at a distance of 40 cm from the convex mirror, calculate:
- the position of the image
- the focal length of the convex mirror.
Define the following term in relation to concave mirror.
Focal length
What is the relationship between the focal length and radius of curvature?
Complete the following diagrams shown in the below figure by drawing the reflected ray for each incident ray.
Numerical problem.
The radius of curvature of a spherical mirror is 25 cm. Find its focal length.
