Question

Light passes from medium one (v₁) to medium two (v₂). If v₁ < v₂ then at the boundary A) f increases, λ decreases. B) f does not change, λ increases. C) f decreases, λ increases. D) f does not change, λ decreases.

Quizplus · Accepted Answer

When light passes from one medium to another, its frequency (f) remains constant because frequency is determined by the source of the light. However, if the speed of light in the second medium (v₂) is greater than in the first medium (v₁), the wavelength (λ) increases because wavelength is directly proportional to the speed of light in the medium (λ = v/f).
