Question

parallel beam of white light is incident normally on a distraction grating it is a notice that a second order and third order spectra partially overlap which wavelength in the third order spectrum appeared in the same angle as the wavelength of 600 NM in the second order spectrum

Answer 1

Answer:

I think ur answer is,

Explanation:

The concept of ur questions answer is ::
