Q.	An optically plane surface reflects a beam of light –
A.	as a parallel beam in one direction
B.	as diffused beams in all d rections
C.	as parallel beams in all direactions
D.	as a diffused beam in one direction
Answer» A. as a parallel beam in one direction
Explanation: An optically plane surface reflects a beam of light as a parallel beam in one direction. The set of incident rays are reflected as a set of rays. In other words, a beam of light is reflected as a beam of light if the mirror is plane and its reflecting surface is smooth. This type of reflection of a set of rays is called Specular Reflection.
