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

ایک ڈفریکشن گریٹنگ کے ڈفریکشن پیٹرن کے سنٹرل میکسما کی شدت پر سیٹوں کی تعداد بڑھانے کا کیا اثر ہے؟

Intensity of central maxima will decrease

Intensity of central maxima will increase

There will not be any effect

Diffraction pattern will disappear

Increasing the number of slits on a diffraction grating will increase the intensity of the central maximum of the diffraction pattern.
