Diffraction by a Single Slit Questions and Answers PDF Download
If wave's first side diffraction maximum is 15° and is coinciding with first minimum of red light, then wavelength of light is
- 430 nm
- 120 nm
- 350 nm
- 1200 nm
If a slit of width 'a' is illuminated by white light, then value of 'a' at which the first minimum for red light of wavelength 650 nm appears at θ=15°, is
- 25 µm
- 2.5 µm
- 250 µm
- 25 m
If 'a' is single slit width and θ is angle of first dark fringle, then path length difference in single slit diffraction is equals to
- asinθ
- acosθ
- atanθ
- acotθ
In a single slit diffraction experiment, dark fringles are produced where the path length differences between top and bottom rays are
- 90° shift with each other
- 180° shift with each other
- 120° shift with each other
- equal
