For Young's double slit experiment, two statements are given below:

Statement I : If screen is moved away from the plane of slits, angular separation of the fringes remains constant.

Statement II : If the monochromatic source is replaced by another monochromatic source of larger wavelength, the angular separation of fringes decreases.

In the light of the above statements, choose the correct answer from the options given below:

View answer and explanation

Correct option: A

Statement I is true but Statement II is false

Option A (Statement I is true but Statement II is false) is correct because angular separation depends on wavelength but not screen distance.
