MCQ (More than One Correct Answer)

-1

A light source, width emits two wavelengths $$\lambda$$₁ = 400 nm and $$\lambda$$₂ = 600 nm, is used in a Young's double-slit experiment. If recorded fringe widths for $$\lambda$$₁ and $$\lambda$$₂ are $$\beta$$₁ and $$\beta$$₂ and the number of fringes for them within a distance y on one side of the central maximum are m₁ and m₂, respectively, then

$$\beta$$₂ > $$\beta$$₁

m₁ > m₂

from the central maximum, 3rd maximum of $$\lambda$$₂ overlaps with 5th minimum of $$\lambda$$₁

the angular separation of fringes of $$\lambda$$₁ is greater than $$\lambda$$₂

-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
