Question

How many orders of spectra possible for grating of 15000 lines per inch ?

Answer 1

Answer:

Step 1 of 5

The condition of diffraction is given by the following equation.

Here, d is the slit separation, m is the order of diffraction, is the wavelength, and is the diffraction angle.

The slit separation d is the reciprocal of total number of lines N on the grating.
