Question

Problem 2:  A ray of light is incident on an air/water interface. The ray makes an angle of θ1 = 44 degrees with respect to the normal of the surface. The index of the air is n1 = 1 while water is n2 = 1.33.

Part (a) Choose an expression for the angle (relative to the normal to the surface) for the ray in the water, θ2. SchematicChoice   : Part (b) Numerically, what is the angle in degrees? Numeric   : A numeric value is expected and not an expression. θ2 = __________________________________________ Part (c) Write an expression for the reflection angle ψ, with respect to the surface. Expression   : ψ = __________________________________________ Select from the variables below to write your expression. Note that all variables may not be required. α, β, θ, θ1, a, d, g, h, i, j, k, m, P, S, t Part (d) Numerically, what is this angle in degrees? Numeric   : A numeric value is expected and not an expression. ψ = __________________________________________ n 01 V n2
