Anti-reflective coatings on lenses use thin-film interference to eliminate the reflection of a particular color. Suppose a glass lens (ng = 1.53) is covered with a thin film (nf = 1.31) to prevent green light (λ = 534 nm) from being reflected.

Light incident on a surface at an angle of 45 degrees undergoes diffused reflection. At what angle will it reflect?

A ship on the surface of the ocean receives a sonar echo back from an underwater object. The echo path from the object to the ship is at an angle of 35 degrees above the horizontal and takes 3s to return. (Velocity of sound in sea water = 1500m/s).
