Question

what is diffraction and polarization??​

Answer 1

• Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.

• Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. ... In linear polarization, the fields oscillate in a single direction. In circular or elliptical polarization, the fields rotate at a constant rate in a plane as the wave travels.

Answer 2

1)

diffraction, the spreading of waves around obstacles. ... The phenomenon is the result of interference (i.e., when waves are superimposed, they may reinforce or cancel each other out) and is most pronounced when the wavelength of the radiation is comparable to the linear dimensions of the obstacle is called diffraction.

Formula

d \sin \theta= n \lambda

d = distance between slits

\theta = diffraction angle

n = order number for the maximum

\lambda = wavelength

2)

Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.

In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave.
