Question

State the conditions of steady Intraference pattern​

Answer 1

Explanation:

• The amplitudes of waves must be equal. i.e. the brightness of the two sources should be the same. ... The sources should emit light waves in nearly the same direction. The two interfering waves must be in the same state of polarization.

Answer 2

Answer:

[tex][/tex] State the conditions of steady Intraference pattern.

1. The two sources of light must be coherent that is there is constant phase difference between the light waves emitted by the two sources. (This condition is met only if the two sources are derived from the same source)
2. The two sources of light must be monochromatic that is the light emitted is of the same wave length.
3. The light waves emitted by the two sources must be of equal amplitudes or the sources must be of same intensity.
4. The two sources must be narrow. Point sources of light in the form of illuminated slits are used.
5. The two sources must be close to each other.
6. The two sources should emit waves in nearly the same direction.
