(a) Write one use of concave mirror as well as convex mirror.
(b) Draw ray diagrams for the following cases when a ray of light:
(i) passing through centre of curvature of a concave mirror is incident on it.
(ii) parallel to principal axis is incident on convex minor.
(iii) is incident at the pole of a convex minor.
(iv) passing through focus of a concave mirror incident on it.
(a) Concave mirrors are commonly used in torches, search lights and vehicles headlights to get powerful parallel beam of light. Convex mirrors are commonly used as rear view minors in vehicles.
b) The ray diagrams are shown below :
