4) Complete the calculations for Examples 3, 4, and 5 on page 8 of the lesson "Review of EM Waves". Make sure that you convert the final answer for the wavelengths to nanometers.

3.)The wavelength of red (3.8*10^14)and violet lights(7.5*10^14)

Red 300000000/

Violet 30*10^7/7.5*10^14=4*-7m

4.)The wave of a microwave frequency at 10^10hz

5.)The wave of xray frequency at 10^18hz.
