Each point on a wavefront acts as a point source that produces spherical wavefronts. This behavior is also known as: Fermat's principle false Huygens' principle true Superposition false Constructive interference false Single There are two assumptions made in experiments involving EM waves. One assumption is that the source of light is coherent. What is the other assumption? The light wave is transverse false The light wave behaves as a ray false The light wave is a particle false The light wave is monochromatic true Single He demonstrated the wave nature of light through his famous double-slit experiment. Pierre Gasendi false James Clerk Maxwell false Thomas Young true Rudolf Hertz false Single In an interference pattern produced by light passing through n slits, the bright bands correspond to regions where: light undergoes destructive interference false light undergoes constructive interference true light rays tend to be concentrated false random particles of light concentrated false Single The dark bands adjacent to both sides of the central peak of an interference pattern is referred to as the: zeroth dark false first dark true central dark false principal dark false Single Thin film interference only applies in a situation where light passes through three successive mediums with respective refractive indices A, B, and C and in which: A > B > C false A < B < C false A > B < C false A < B > C true Single When you place your thumb and index finger very close to each other in front of a source of bright light, you will see dark fringes form within the narrow gap between your fingers. This phenomenon shows: dispersion false diffraction true destructive interference false thin film interference false Single What distance away from the center of the interference pattern produced by a single slit will you find its third dark fringe if the width of the slit is 1 unit? λR/3 false 3R false λR false 3λR true Single How many dark fringes will form in the interference pattern formed by four slits? 1 false 2 false 3 true 4 false Single Which of the following situations occur as a consequence of thin film interference? grease in water producing rainbow-like pattern of colors true the formation of a rainbow during a light rain false white light passing through a glass prism forming a colored band false tinted car windshields reducing the glare of the sun false Single
