Hi,

This was really useful but it would be good if you could post the answer sheet as I dont have much of a clue if I got it right or not!

Cheers, Rory

Did you look at the links underneath?

I don’t understand Q1) A how do I find the SPEED when I only have the TIME. To find the SPEED you need the TIME and DISTANCE. (S=D/T)

The clue is in the question. It says STATE, not CALCULATE, so you don’t have to use a relationship to obtain the answer. Use your knowledge of another region of the ELECTROMAGNETIC SPECTRUM to get the answer.
