- Speculate as to s1at physical process might be responsible for light traveling more slowly in a medium than in a vacuum.arrow_forwardA light beam in air is incident on the surface of a pond, making an angle of 20° with respect to the surface. What are the angles of reflection and refraction?arrow_forwardIn what substance in Table 1.1 is the speed of light 2.290108 m/s?arrow_forward
- Check Your Understanding in Example 1.6, we had n1n2. If n2were decreased such thatn1n2and the speed of light in medium 2 is faster than in medium 1, what would happen to the length of AA’ ? What would happen to the wave front A’B and the direction of the refracted ray?arrow_forwardWhen a light ray crosses from water into glass, it emerges at an angle of 30with respect to the normal of the interface. What is its angle of incidence?arrow_forwardCheck Your Understanding What happens at Brewster’s angle if the original incident light is already 100% vertically polarized?arrow_forward
- How is the difference in paths taken by two originally in-phase light waves related to whether they interfere constructively or destructively? How can this be affected by reflection? By refraction?arrow_forwardCheck Your Understanding In the preceding example. how much distance inside the block of flint glass would the red and the violet rays have to progress before they are separated b 1.0 mm?arrow_forwardSuppose that in the preceding problem the light incident on P1 is unpolarized. At the determined value of , shat fraction of the incident light passes through the combination?arrow_forward
- Check Your Understanding At the surface between air and water, light rays can go from air to water and from water to air. For which ray is there no possibility of total internal reflection?arrow_forwardWhat is the speed of light in air? In crown glass?arrow_forwardDoes the fact that the light flash from lightning reaches you before its sound prove that the speed of light is extremely large or simply that it is greater than the speed of sound? Discuss how you could use this effect to get an estimate of the speed of light.arrow_forward
