A phase difference of 100° corresponds to what wavelength difference?

Question

Quizplus · Accepted Answer

A phase difference of 360° corresponds to one wavelength difference. Therefore, a phase difference of 100° corresponds to a wavelength difference that is a fraction of a wavelength. Using the formula δ = (2π/λ)d, where δ is the phase difference, d is the distance between the sources, and λ is the wavelength, we can rearrange to solve for the wavelength difference (Δλ): Δλ = λ(Δδ/360) = λ(100/360) = λ(5/18). Therefore, the wavelength difference is 5/18 of the wavelength, which corresponds to C.
