Interference of Light

Problem 5.72

A plane light wave falls on Fresnel mirrors with an angle α=2.0′\alpha=2.0^{\prime} between them. Determine the wavelength of light if the width of the fringe on the screen Δx=0.55 mm\Delta x=0.55 \mathrm{~mm}

Reveal Answer
λ=2αΔx=0.64μm\lambda=2 \alpha \Delta x=0.64 \mu \mathrm{m}
