Question

what is the the ratio of path difference to the phase difference of light wave in radian?​

Answer 1

Answer:

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
