Who said the radiation had to be in the form of visible light? :)

Actually, the OP's question is too vague to be definitively
answerable. Too many unknowns. Too many assumptions to be made.

I have a hunch the teacher is not looking so much for a right
or wrong answer, but is looking for the students ability to
derive an answer and to back up that answer with argument. The
teacher is not testing to see if you know the answer, but if
you can deduce an answer and how you come to that conclusion.
A test of your ability to think and reason.
