Use the following information to answer the next two questions 1. The wave theory of light provides the best explanation for which pair of light properties? Several transparent substances are arranged in layers so that their surfaces are parallel. A light ray is directed at the substances, as shown below. Straight-line propagation and refraction TO.-368' air * = 1.00 Interference and diffraction water .. =1.33 Reflection and dispersion class mom -1:50 Dispersion and the photoelectric effect plastic memm = 1.40 2. Electromagnetic radiation travels through space as magnetic fields and electric fields. The radiation travels in a direction that is to the electric and magnetic fields The light travels fastest through i - changing ii - constant iii - parallel glass i - changing ii - changing iii - parallel air plastic i - constant ii - changing ili - perpendicular water i - changing ii - changing ili - perpendicular 5. Using the information from the previous question, calculate the angle of refraction In the plastic, Op- (Record your 3 significant digit answer) 3. If certain X-rays have a frequency of 2.15 x 1020 Hz, then the period of these X- rays, expressed in scientific notation, is a.b x 10" s. The values of a, b, c, and d Your answer: ver the next question are . (Record your 4 digits answer) A raly of light travelling from oil to air refracts at 90" as shown Your answer: 0000 refracted ray 7. An object is 4.5 m tall and is located 7.0 m in front of a concave mirror that has a focal length of 5.0 m. The size and orientation of the image are, respectively, 11 m and inverted 1.9 m and erect If the wavelength of the light is 6.02 x 10/ m in air, its wavelength in oil was 1.9 m and inverted 6.02 x 10 m 7.86 x 10 m 11 m and erect 4.61 x 10 m 15. A student uses a filter to analyze a light source. As the filter is rotated the 3.87 x 10% m transmitted light alternately dims and brightens. This observation can be used as evidence to support the hypothesis that the light source is partially polarized 17. Small flashes of blue light are observed when air bubbles in water are exposed to ultrasound. The frequency of the blue light is 7.14 X 1014 Hz. The minimum sound energy required to produce one photon of blue light is eV. (Record varies in color your three digit answer.) is monochromatic Your answer: varies in intensity
