1)An electromagnetic wave has a wavelength of 6.2 x 10^14 n. What is the frequency of the wave?
3.00 x 10^8 * 6.2 x 10^14
1.8 x 10^24 = frequency
2)The velocity of an electromagnetic wave depends on:
its wavelength and frequency
Both are wrong. In one, I wonder where you got the first formula.
2) What determines the veloicity oflight in glass? You need to think about the medium.
