A laser produces light of wavelength λ. The light is directed through two slits that are separated by a small distance. On the other side of the slits is an interference pattern of alternating dark (black) and bright bands. What is the wavelength of the light in the bright bands?

λ
2λ
9λ
0.5λ

Its either 2 or .5 cause it alternates

aaronq · Answer

I dont think the wavelength changes as a light wave diffracts, because it's not changing speed

akohl · Answer

Depends does frequency change

aaronq · Answer

nope it doesnt

K thanks

aaronq · Answer

no problem, i gotta get going though. later
