Answer:
Image Formation by Spherical Mirrors
Guidelines for Rays Falling on the Concave and Convex Mirrors
When a ray strikes concave or convex mirrors obliquely at its pole, it is reflected obliquely.
When a ray, parallel to principal axis strikes concave or convex mirrors, the reflected ray passes through the focus on the principal axis.
When a ray, passing through focus strikes concave or convex mirrors, the reflected ray will pass parallel to the principal axis.
A ray passing through the center of curvature of the spherical mirror will retrace its path after reflection.
Image Formation By Concave Mirror
By changing the position of the object from the concave mirror, different types of images can be formed. Different types of images are formed when the object is placed:
At the infinity
Beyond the center of curvature
At the center of curvature
Between the center of curvature and principal focus
At the principal focus
Between the principal focus and pole
Image Formation By Convex Mirror
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror.
