Use the following information to answer the next question ver the next question A radio signal is sent from a source and reflected from a satelite in space. It is Students use various apparatus to investigate optical phenomena. During their investigations, they make the following eight observations. Michelson used rotating mirrors, similar to those shown below, to calculate the speed detected back on Earth. If it takes 2.00 x 10 * s for the signal to complete the path of light. from the source to the detector, then the signal travels a distance of Observations plight rounce 60.0 km The apparatus produces a continuous spectrum with white light. 2 The apparatus produces a bright-line spectrum with white light. 30.0 km The apparatus produces an interference pattern with monochromatic light. 1.50 x 109 km The apparatus produces a single bright line with monochromatic light 5 The apparatus bends red light through a smaller angle than it bends observer 3.00 x 109 km blue light. The apparatus bends red light through a larger angle than it bends Light is emitted from the light source, reflects from mirror surface X to the plane blue light. mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The The apparatus produces a single spectrum when white light is incident light then continues to the observer. 12. A diffraction grating with 4.50 x 103 lines/m produces a second-order bright line perpendicular to the apparatus, The distances from the light source and the observer to the rotating mirrors are 25.0" from the central maximum. The wavelength of the incident light is, expressed The apparatus produces multiple spectra when white light is incident negligible. The distance from the rotating mirrors to the plane mirror is 35 0 kim in scientific notation, is a.bc x 10 m. The values of a, b, c, and d are perpendicular to the apparatus. (Record your 4 digits answer) 11. If the mirrors are rotating at 480 news, the speed of light calculated from the given information is Your answer: DOOO 14. Four observations that could be produced using only a diffraction gratings are numbered: (Record all four digits of your answer in lowest-to- 2 98 x 10 m/s highest numerical order.) 1.34 x 10 m/'s Your answer: 7.44 x 10m/'s 9. A student uses an optical bench and places a burning candle with a 1.00-cm-high flame at a distance of 20.0 om from a convex mirror with a focal length of 15.0 cm. 3.36 x 10' m/s 02: 03 The image is air O virtual, erect, and larger. 15. A student is given a light source and a filter. She is asked to use both to hypothesize as to the nature of the light and Ster, based on her observations. One observation is that as the Siter is rotated, the light dims and brightens repeatedly. real, erect, and larger The student hypothesizes that the water 1 06 light is monochromatic and the filter is unpolarized. virtual, erect, and smaller. light is composed of all wavelengths and the filter is unpolarized. real, inverted, and smaller light unpolarized and the filter is polarized. 13. Match the angles of incidence, reflection and refraction with the angles in the light and the filter are both polarized. diagram: angle of incidence (Record in the first box) angle of reflection (Record in the second box) angle of refraction (Record in the third box) Your
