Which of the following is least reasonable regarding light waves?    a) Ultraviolet light has a shorter wavelength and lower frequency than visible light.   b) Frequency is equal to the speed of the wave divided by the wavelength of the wave.    c) An apple which appears red in white light would appear black when illuminated by blue light.   d) Light visible to the human eye is the part of the electromagnetic spectrum with wavelengths roughly in the range of 400-700 nanometers.   e) A banana appears yellow because it reflects red and green colors while absorbing blue.

Learning Goal: To understand polarization of light and how to use Malus's law to calculate the intensity of a beam of light after passing through one or more polarizing filters. The two transverse waves shown in the figure (Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized in the +x direction whereas the lower wave is polarized in the +y direction. In general, waves can be polarized along any direction. Recall that electromagnetic waves, such as visible light, microwaves, and X rays, consist of oscillating electric and magnetic fields. The polarization of an electromagnetic wave refers to the oscillation direction of the electric field, not the magnetic field. In this problem all figures depicting light waves illustrate only the electric field. A linear polarizing filter,…
