Question

In which unit is the wavelength of an electromagnetic wave commonly measured?

A. s^–1
B. kg
C. nm
D. J

Answer 1

E = hv = h\(\sf \frac{c}{\lambda}\) where c = speed of light, and is measured in m/s, so if you need to cancel meters, what must wavelength be?

Answer 2

lol look at this link http://en.wikipedia.org/wiki/Wavelength

Answer 3

i guess so

Answer 4

@aaronq the answer is A right?

Answer 5

wavelength is a distance, therefore it needs to have units of distance. Only one of the options has units of distance

Answer 6

ohhh C right?

Answer 7

im not supposed to be giving you answers :S
