Homework Help: Physics

Posted by Olivia on Tuesday, September 9, 2008 at 5:44pm.

Ok so I think I have this correct, but I'm not sure.

The question is: what is the frequency of green light, which has a wavelength of 4.90 x 10 ^-7 m?

Since all electromagnetic waves travel at
3.00 x 10^8 m/s (c), and
c= wavelength x frequency,

The problem is:
(3.00 x 10^8) / (4.90 x 10^-7) = frequency

Right?

I got .61 x 10^15 as a result.

Is this right?
