Which of the following statement best describes the optical element hidden by the black box in the diagram given the behaviour of the rays of light incident on it? A) The block box must contain a concave lens. B) The black box must contain a concave lens. C) The black box must contain a concave mirror. D) The black box must contain a convex mirror. E) The black box must contain a plane mirror. Which of the following has the smallest frequency? A) gamma rays B) infrared C) microwaves D) radio waves E) ultraviolet F) visible light

Explanation / Answer

1. the box must contain a plain mirror attatched on the top surface as the way it reflects its definitely plane mirror.

the angle of reflection seems perfectly eual to angle of incidence.

2. radio waves , as it has the largest of frequency here and from lambda*freuency = c , they are inversely proportional.
