The difference between the wavelengths of the stokes line and anti-stokes lines in the Raman spectrum of H-Br molecule is 100 Å . If the wavelength of the anti-stokes line is 5000 Å , then the wavelength of the incident radiation is

Step-by-step solution

Stokes lines are the radiation of certain wavelengths present in the line spectra, that is associated with the phenomena of fluorescence and the Raman effect. Anti-stokes lines are produced due to already excited atoms or molecules. These lines are symmetrical about the main lines and the wavelength of anti-stokes lines is less than the main line. So, if the difference between wavelengths of stokes line and corresponding anti-stokes line is 100 Å , then the difference between anti-stokes line and main line is 50 Å
