Question

1. A heat lamp is designed to keep food and other things warm. Would it also make a good tanning lamp? Why or why not?

2.The wavelength of an electromagnetic wave is measured to be 0.250 m. What is the frequency of the wave? What type of EM wave is it?

Answer 1

1. becuase it is so hot that it could tan or be used to keep warm.

Answer 2

1 isn't a tanning lamp one which produces UV ? a heat lamp does IR. so no.
2 speed of light = frequency times wavelength. 300,000,000/0.25 = frequency.
