Section C: Give a short answer to the question given below.
Draw ray diagram in each of the following cases to show what happens after reflection to the incident ray when
(a) it is parallel to the principal axis and falling on a convex mirror.
(b) it is falling on a concave mirror while passing through its principal focus.
(c) it is coming oblique to the principal axis and falling on the pole of a convex mirror.
(a) it is parallel to the principal axis and falling on a convex mirror.
(b) it is falling on a concave mirror while passing through its principal focus.
(c) it is coming oblique to the principal axis and falling on the pole of a convex mirror.
(a) Whenever an incoming ray is parallel to the principal axis and strikes a convex mirror, it becomes and its focus following laws of reflection from the mirror.
(b) Whenever an incoming ray strikes a concave mirror while travelling through its primary focus, it must be.
(c) Whenever an incident ray is oblique towards the primary axis and strikes the pole of a convex mirror, it must be .
