A ray of light passes from a denser medium to a rarer medium at an angle of incidence 'i'. If the reflected and refracted rays are perpendicular to each other, the critical angle θc is given by:

What are the characteristics of an image formed by a plane mirror?

Given below are two statements: an Assertion [As] and a Reason [R]. Assertion [As]: A convex mirror cannot form real images of real objects. Reason [R]: Convex mirrors converge the parallel rays of light that are incident on them. Choose the correct alternative:
