Numerical Response #4 Light with a wavelength of 3.78 x 10-7m illuminates double slits that are positioned 2.10 m away from a screen. An interference pattern with fringes 4.55 mm apart is observed on the screen. The distance between the slits, expressed in scientific notation, is a.bc x 10-m. The values of a, b, c, and d are and (Record all four digits of your answer on your Scantron) 12. A student records several observations about the wave nature of light. Which observation can only be explained if light is a transverse wave? A. Light passes through a double slit making an interference pattern on a screen. B. Polarization of light. C. Dispersion of light shining through a prism. 19 88.1 D. Refraction of light from air to water. 13. When performing an experiment similar to Young's double-slit experiment, a student observes that the distance between antinodes triples. The most likely change that the student made in order to observe this effect is that they A. decreased the wavelength of the light to one-third the original. B. decreased the distance from the slits to the screen to one-third the original. C. decreased the intensity of the light to one-third the original. D. decreased the distance between the slits to one-third the original. 10 3 mo 0.01 bsosig el looklo I mo 00:2 8 0
