 No
Interference
Diffraction
1
It arises due to superposition of two wave fronts coming from the coherent sources.
It is produced due to the superposition of secondary wavelets originating from the different parts of the same wavefront.
2
All bright fringes are of the same intensity.
All bright fringes are not of the same intensity.They are of varying intensity.
3
The width of the interference fringes are usually equal.
Diffraction fringes are never of the same width.

Two polarizers are placed at crossed position (i.e. having an angle of 90 between them ), a third polarizer making an angle  with the first one is placed between them. An unpolarized light of intensity I0 is incident on the first oneand passes through all the three polarizers. Find the light intensity of the emergent beam.
