The speed of light c in a vacuum is 2.997 × 108 m/s. Given that the index of refraction in benzene is 1.501, what is the speed of light benzene in benzene? Given that the index of refraction in zircon is 1.923, what is the speed of light Uzircon in zircon? Ubenzene- m/s Dzircon = m/s

In what substance in Table 1.1 is the speed of light 2.290108 m/s?

The index of refraction for water is about 43. What happens as a beam of light travels from air into water? (a) Its speed increases to 43c, and its frequency decreases. (b) Its speed decreases to 34c, and its wavelength decreases by a factor of 34. (c) Its speed decreases to 34c, and its wavelength increases by a factor of 43. (d) Its speed and frequency remain the same. (e) Its speed decreases to 34c, and its frequency increases.

A scuba diver training in a pool looks at his instructor as shown in Figure 25.53. What angle does the ray from the instructor’s face make with the perpendicular to the water at the point where the ray enters? The angle between the ray in the water and the perpendicular to the water is 25.0°. Figure 25.53 A scuba diver in a pool and his trainer look at each other.
