Question

What is the effect of increasing the number of slits on the intensity of Central maxima of diffraction pattern of a diffraction grating?​

Answer 1

Answer:

Intensity of central maxima will increase

Answer 2

On increasing the number of slots on the intensity of Central maxima of the diffraction pattern of a diffraction grating, the intensity of central maxima will increase.

• The grating intensity is proportional to the square of the number of slits illuminated.
• Increasing the number of slits makes the diffraction maximum sharper.
• Increasing the number of slits makes the diffraction more intense.
