Solutions Check the best answer. 1. Which is NOT true of the light from the sun that we see when we look at the sky on a clear day? The blue color arises from the ω 4 dependence of the scattered intensity. The skylight is preferentially polarized with E perpendicular to the plane containing the incident and scattered rays. The degree of polarization of the skylight is the same no matter in what direction we look. [Maximum when we look at right angles to the sun’s rays.] The reddish color of direct sunlight at sunset arises because of the 4 dependence of the scattered intensity. Check T or F depending on whether the statement is true or false. 2. For light incident from air onto a glass plate, the intensity of the re±ected light is greater, for all angles of incidence other than 0 or π /2 , if the E-²eld of the incident light is perpendicular to the plane of incidence rather than in that plane. 1
