YDSE: Fringe Width & Fringe Positions
Given below are two statements:
Statement I: In a Young's double slit experiment, the angular separation of fringes will increase as the screen is moved away from the plane of the slits
Statement II: In a Young's double slit experiment, the angular separation of fringes will increase when monochromatic source is replaced by another monochromatic source of higher wavelength In the light of the above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (c)
- Angular separation does not depend on : Statement I is false.
- , so a higher wavelength increases it: Statement II is true.
- So the answer is (c).
