Wave Optics question

2008 · Shift 1 · Q56

JEE AdvancedPhysicsWave OpticsMultiple correct+4 / −2
In a Young's double slit experiment, the separation between the two slits is d and the wavelength of the light is λ\lambdaλ. The intensity of light falling on slit 1 is four times the intensity of light falling on slit 2. Choose the correct choice(s).
  1. A
    If d=λd=\lambdad=λ, the screen will contain only one maximum
  2. B
    If λ<d<2λ\lambda \lt d \lt 2\lambdaλ<d<2λ, at least one more maximum (besides the central maximum) will be observed on the screen
  3. 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
  4. 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
