STANDARD Physics Young's Double Slit Experiment Assertion Reason Question
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:
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
Statement I is true but Statement II is false.
Statement I is false but Statement II is true.
Correct Answer
Detailed Explanation
Statement I is true because the angular separation depends on the wavelength and slit separation, not the distance to the screen. Statement II is false because increasing the wavelength increases the angular separation.
