Document Summary

33-3 radiation pressure surface: when a surface intercepts electromagnetic radiation, force and pressure is exerted on the. If the radiation is totally absorbed (total absorption) by the surface, the force is expressed as radiation. represents the intensity of the radiation. represents the area of the surface perpendicular to the path of the. The light that outputs from the polarizing sheet is polarized parallel to the polarizing direction of the sheet. This is graphically displayed in the following image: If the original light is initially unpolarized, the output or transmitted intensity is half the original: The angle of incidence (the angle of the ray which has encountered the boundary) is always equal to the angle of reflection ( Snell"s law states that the angle of refraction is related to the angle of incidence by represent the indexes of refraction of the media in which the incident and refracted rays travel.

Electromagnetic waves transport energy. This problem shows you which parts of the energy are stored in the electric and magnetic fields repsectively and also makes a useful connection between the energy density of a plane electromagnetic wave and the poynting vector.

In this problem we explore the properties of a plane electromagentic wave traveling at the speed of light c along the x axis through vacuum. Its electric and magnetic fields are as follows:
