Question

calculate the wavenumber and frequency of yellow radiation having wavelength 500a​

Answer 1

I don't know this answer but I will think

Answer 2

Answer:

Explanation:

wavelength of light= 500x10^-10m

frequency is given by=c/wavelength

3x10^8/500x10^-10

3x10^8/5x10^-8

3/5x10^16

wave number is reciprocal of wavelength

 wave number=1/wavelength=1/500x10^-10=10^10/500=0.2x10^8 =2x10^7
