Question

Write two difference between interference and diffraction of light wave

Answer 1

Difference table of interference and diffraction:
Interference

1: Interference is due to interaction of light coming from two different wave fronts originating from the same source.

Diffraction

1:Diffraction is due to interaction of light coming from different parts of the same wave front.

Interference

2:Interference fringes are of the same width.

Diffraction

2:Diffraction fringes are not of the same width.

Interference

3: All bright fringes are of the same intensity.

Diffraction

3:All bright fringes are not of the same intensity.

Interference

4:All point of minimum intensity are perfectly dark.

Diffraction

4:All point of minimum intensity are not perfectly dark.

Interference

5:The spacing between fringes is uniform.

Diffraction
5:The spacing between fringes is not uniform
