## anonymous one year ago what is the frequency of a 670nm lightwave? multiple choice answers in comments.

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

3. anonymous

but i only know one of those variables?

4. anonymous

Which ones do you know?

5. anonymous

wavelength

6. anonymous

I gave you speed of light (c)

7. anonymous

oh okay. so 3 * 10^8 = 670v so v= 447761.194 but how do i convert that into one of the multiple choice answers?
