If I0 = 20.0 W/m2 , θ0 = 25.0 degrees , and θTA = 40.0 degrees , what is the transmitted intensity I1 Learning Goal:To understand polarization of light and how to use Malus's law tocalculate the intensity of a beam of light after passing through oneor more polarizing filters.The two transverse waves shown in the figure(Figure 1) both travelin the +z direction. The waves differ in that the top wave oscillateshorizontally and the bottom wave oscillates vertically. The directionof oscillation of a wave is called the polarization of the wave. Theupper wave is described as polarized in the +x direction whereasthe lower wave is polarized in the +y direction. In general, wavescan be polarized along any direction.Recall that electromagnetic waves, such as visible light,microwaves, and X rays, consist of oscillating electric and magneticfields. The polarization of an electromagnetic wave refers to theoscillation direction of the electric field, not the magnetic field. Inthis problem all figures depicting light waves illustrate only theelectric field.A linear polarizing filter, often just called a polarizer, is a device thatonly transmits light polarized along a specific transmission axisdirection. The amount of light that passes through a filter isquantified in terms of its intensity. If the polarization angle of theincident light matches the transmission axis of the polarizer, 100%of the light will pass through, so the transmitted intensity will equalthe incident intensity.

Radio waves and microwaves are used in therapy to provide “deep heating” of tissue because the waves penetrate beneath the surface of the body and deposit energy. We define the penetration depth as the depth at which the wave intensity has decreased to 37% of its value at the surface. The penetration depth is 15 cm for 27 MHz radio waves. For radio frequencies such as this, the penetration depth is proportional to √λ, the square root of the wavelength. What is the wavelength of 27 MHz radio waves?A. 11 m B. 9.0 m C. 0.011 m D. 0.009 m
