Calculate the frequency of electromagnet...

Calculate the frequency of electromagnetic radiation having the wavelength 3 `mu`. Calculate the wave number corresponding to it. (`1 mu = 10^(-6)` m)

Text Solution

Verified by Experts

`v=c/lamda=(3xx10^(8))/(3xx10^(-6))=1xx10^(14)Hz`
Wave number `=1/lamda=1/(3xx10^(-6))=0.3333xx10^(6)m^(-1)`
