Question

condition for maximum intensity in diffraction grating​

Answer 1

Answer:

The condition for maximum intensity is the same as that for the double slit or multiple slits, but with a large number of slits the intensity maximum is very sharp and narrow, providing the high resolution for spectroscopic applications.

Answer 2

Condition for maximum intensity in the diffraction grating​ is as follows:

• The maximum intensity condition is the same as for a double slit.
• Because the slit spacing in a diffraction grating is so tiny, the angular separation of the maxima is usually significantly greater.
• For the separation of spectral lines associated with atomic transitions, the diffraction grating is an extremely valuable tool.
