A plane electromagnetic wave with a time-averaged Poynting vector 〈S!〉 is incident on a long prism made from a conducting material which has a cross-section in the shape of an equilateral triangle, with side length a (see figure below). Assume that the prism is large compared to the wavelength of the electromagnetic wave and that scattering from the corners can be neglected. In other words, it can be assumed that the outgoing waves are produced by specular reflection from the sides of the prism. 60 60° Top view Side view Find the radiation force per unit length (magnitude and direction) on this object in terms of (S), the speed of light c, and the side lengeth a. You may use the result derived in lectures: P--!(3,1 cos2 θ-
