Q24 · Physics
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:
- 1Statement I is false but Statement II is true.
- 2Both Statement I and Statement II are true.
- 3Both Statement I and Statement II are false.
- 4Statement I is true but Statement II is false.Official answer
