To observe diffraction, the size of the obstacle

Options

  1. Ahas no relation to wavelength.
  2. Bshould be ( / 2 ), where ( ) is the wavelength.
  3. Cshould be much larger than the wavelength.
  4. Dshould be of the order of wavelength.

Correct answer

D. should be of the order of wavelength.

Step-by-step solution

Diffraction is phenomena of spreading of light around obstacles. Diffraction of light occurs when light passes through a slit that has size of the order of wavelength of light or evensmaller than it.
