Modified from College Physics , 7 th Ed., Serway, Faughn, and Vuille. For the quizzes and tests, you should know all the concepts and equations in this summary. Section 22.1: The Nature of Light Light has a dual nature. In some experiments it acts like a wave, in others like a particle, called a photon by Einstein. The energy of a photon is proportional to its frequency, hf E = [22.1] where is Planck's constant . s J 10 63 . 6 34 × = h Light is neither a wave nor a particle. We know how light behaves, but it is difficult for us to know what light is. Section 22.2: Reflection and Refraction In the reflection of light off a flat, smooth surface, the angle of incidence, 1 θ , with respect to a line perpendicular to the surface is equal to the angle of reflection, 1 : 1 1 = [22.2] Light that passes into a transparent medium is bent at the boundary and is said to be refracted . The angle of refraction is the angle the ray makes with respect to a line perpendicular to the
