In Huygens' proof of the law of reflection, why are the angle of incidence and the angle of reflection equal?
The wavelets in the backward direction cancel, and the rest bend
The wavelet from the near end of the wavefront and the far end of the wavefront travel equal distances in the same time, in the same medium
The wave is slower after the reflection, and the wavefront turns
The mirror takes away half of the energy, and the rest leaves at the same angle

← Violet light has a wavelength of 390 nm in air. What is its wavelength in a plastic of refractive index 1.37?
A screen is lit by two coherent laser beams. Each beam alone would light a spot on it with 2.5 W/m². At the spot, the crests of one beam arrive a quarter of a cycle after the crests of the other. What is the intensity of the light there? →
