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
\( \mathrm{P} \) correct choice(s).
(A) If \( \mathrm{d}=\lambda \), the screen will contain only one maximum
W
(B) If \( \lambda\mathrm{d}2 \lambda \), 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 and bright fringes will increase
