Question 39
H

A source produces visible light from changes in atoms and gamma rays from changes in nuclei. Both radiations are absorbed by surrounding material. Which statement correctly combines the origin, interaction and potential danger of the radiation?

[1]
A

Both emissions involve energy loss; absorption removes energy; visible has the higher frequency.

B

Both emissions involve energy loss; absorption transfers energy; gamma has the higher frequency.

C

Both emissions involve energy gain; absorption transfers energy; visible has the higher frequency.

D

Both emissions involve energy gain; absorption removes energy; gamma has the higher frequency.
