E) The black box must contain a plane mirror. Which of the following has the smallest energy? A) gamma rays B) infrared C) microwaves D) radio waves E) ultraviolet F) visible light

Explanation / Answer

B.1

The reflection of parallel beam light from a sperical mirror never become parellel beam of rays.only the plain morror reflects the parallel beam as parellel beam.

hence option E is correct.

B.2

the wavelength of radio waves is largest and the frequency is smallest.

hence the option D is the nswer.
