Question

what is the frequency of a 670nm lightwave? multiple choice answers in comments.

Answer 1

\[c=\lambda v\]
c is the speed of light at 3.00 x 10^8 m/s
\[\lambda=wavelength\]
v=frquency

Answer 2

but i only know one of those variables?

Answer 3

Which ones do you know?

Answer 4

wavelength

Answer 5

I gave you speed of light (c)

Answer 6

oh okay. so 3 * 10^8 = 670v
so v= 447761.194

but how do i convert that into one of the multiple choice answers?
