Free-Response: Air ( 1.00) #1) in an experiment, a beam of red light of wavelength 675 min air passes from glass into air, as shown above. The incident and retracted anales are, and respectively, in the experiment, angle Oz is measured for vanous angles of incidence and the sines of the anglas are used to obtain the line shown in the following graph 0.1 0.2 0.3 0.4 0.6 0.7 Sin e a Assuming an index of refraction of 1.00 for air, use the graph to determine a value for the index of refraction of the glass for the red light. Explain how you obtained this value. b. For this red light, determine the following. The frequency in air it. The speed in glass i. The wavelength in glass c. The index of refraction of this glass is 1.66 for violet light, which has wavelength 425 nm in air Given the same incident angle 01, show on the ray diagram at the top of the page how the refracted ray for the violet light would vary from the refracted ray already drawn for the red light Sketch the graph of sin a versus sin for the violet light on the figure above that shows the same graph already drawn for the red light d. Determine the critical angle of incidence 8c, for the violet light in the glass in order for total internal reflection to occur
