  1. This is a fairly straightforward question: C(speed of light)=f(frequency)times wavelength. You know the frequency and speed of light... just devide the speed of light by the freuquency and you get 6.38x10^-7m. Perhaps you forgot to convert the speed of light from kilometers into meters? If you need any more help, just contact me on yahoo messenger. My name is kate.grass@yahoo.com


  2. The relation between frequency and wavelength is



        frequency=velocity of light/wavelength

    wavelength=(3*10^8)/4.7*10^14

  3. Thats easy. You'll get the answer straight away by dividing the velocity with the frequency. but u'll first have to convert the velocity into m/s bcoz thats the S.I unit.
