light of wavelength 633 nm is incident on a narrow slit. the angle between the first diffraction minimum on one side of the central maximum and the first minimum on the other side is 1.20 degrees. what is the width of the slit?

Respuesta :

When ray estimation of geometric optics cannot be used, wave opticsā€”also known as physical opticsā€”is concerned with the study of numerous phenomena like polarization, diffraction, interference, and other occurrences.

wavelength of light = 633 nm = 633*10-9 m,

the angle Īø = 1.20 / 2 = 0.6

condition for diffraction minimum,

d sin Īø = mĪ»

for first minimum n = 1

d sin Īø = Ī»,

and as a result,

slit width d = Ī» / sinĪø = (633*10-9 m) / sin0.6 = 6.04Ɨ10 āˆ’5m

The various wave optics kinds are:

  • Coherent and Incoherent Wave Addition
  • Diffraction.
  • The Huygens Rule.
  • Young's Experiment with Light Wave Interference.
  • Polarisation.
  • Using the Huygens principle, plane waves can be refracted and reflected.
