MCQ (More than One Correct Answer)

-2

In a Young's double slit experiment, the separation between the two slits is d and the wavelength of the light is $$\lambda$$. The intensity of light falling on slit 1 is four times the intensity of light falling on slit 2. Choose the correct choice(s).

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

If $$\lambda < d < 2\lambda$$, at least one 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
