Physics - Wave Optics Question with Solution | TestHub

If $d=\lambda$, the screen will contain only one maximum

If $\lambda <d<2\lambda$, at least two more maximum (besides the central maximum) will be observed on the screen

If the intensity of light falling on slit 1 is reduced so that it becomes equal to that of slit 2, the intensities of the observed dark and bright fringes will increase

If the intensity of light falling on slit 2 is increased so that it becomes equal to that of slit 1 , the intensities of the observed dark and bright fringes will increase
