Question

Using Young's double slit experiment give the relation between the path difference and the phase difference of the light rays​

Answer 1

Answer:

Phase Difference And Path Difference

For any two waves with the same frequency, Phase Difference and Path Difference are related as-

Δx=λ2πΔϕ

Where,

Δx is the path difference between the two waves.

ΔΦ is the phase difference between two waves.

Phase Difference And Path Difference Equation

The difference in the phase angle and difference in path length relation can be written in various ways-

Formula Unit

The relation between phase difference and path difference Δxλ=Δϕ2π No units

Phase Difference Δϕ=2πΔxλ Radian or degree

Path Difference Δx=λ2πΔϕ meter
