What is the frequency and wave number associated with light of wavelength equal to 6000 angstrum

2 answers

Velocity of light (c) = 3*10^8 m/s

You should know velocity = wavelength * frequency

Convert the wavelength into meters and solve put it in the above equation. You should get the answer.

And yeah, I ain't no engineer.
Note that you will need to change A to meters; also, wave number = 1/wavelength
