Path difference between two wavefronts emitted from coherent sources is $2.1 μm.$ Phase difference between the wavefronts at that point is $7.692 π$ . Wavelength of light emitted by source will be

Options:

Answer:

Solution:

Phase difference, $ϕ = \frac{2 π x}{λ}$ or $λ = \frac{2 π x}{ϕ}$

$= 2 \times π \times \frac{2.1 \times 10^{- 6}}{7.692 π} = 5460 \times 10^{- 10} m$
