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

A

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

B

If `lambda lt d lt 2 lambda`, at least one more maximum (besides the central maximum) will be observed on the screen

C

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.

D

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 the bright fringes will increase.
