In general, the refractive index decreases as the wavelength of the incident light increases. This phenomenon is called? chromatic dispersion true chromatic aberration false anomalous dispersion false total internal refraction false Single What color has a longer wavelength than yellow? violet false blue false green false orange true Single Which of the following colors of light tends to be least refracted by a medium? blue false green false yellow false red true Single Light is considered unpolarized when: Its E field's orientation is restricted false Its E field takes random directions true Its E field decouples from its B field false Its E field oscillates false Single What is the wave function of an E field that is propagating along the z-axis? Emax sin (kx - ωt) false Emax sin (kx + ωt) false Emax sin (kz - ωt) true Emax cos (kz - ωt) false Single The quotient of the maximum amplitude of the E field of an EM wave over the maximum amplitude of its B field is equal to? 1 false 1 m/s false 3.0 x 10₈ m/s true each other false Single What happens to the intensity of unpolarized light when it passes through a polarizer? It remains the same false It decreases by a factor of 0.5 true It increases by a factor of 0.5 false It becomes equal to 0.5 units false Single What device is used to measure the intensity of polarized light? photocell true polarizer false analyzer false optic fiber false Single This term refers to the tendency of shorter wavelengths of light to be scattered as it propagates through a medium leaving behind longer wavelengths to reach an observer. Rayleigh scattering true Compton scattering false Dynamic Light Scattering false Tyndall effect false Single What is the angle at which incident light becomes totally polarized? Angle of incidence false Angle of reflection false Angle of refraction false Brewster's angle true Single
