- For each ray (#1-4) what is the total phase shift of the ray along the path just due to reflection or refraction at the interfaces. (Your answer will either be zero or pi. Don't need to include phase shift differences due to path length differences).( Please type answer note write by hend )Calculate the critical angle for the light traveling from glass (n glass= 1.54) to air (n=1.00). Express your answer in degrees. Normal format with 3 SF. air
- A ray of light travels through air until it strikes the interface between the air and another medium. The incident ray makes an angle of 0, = 32.0° with the normal, as shown in the figure below. Upon passage into the second medium, the ray is refracted, emerging from the interface at an angle 0, with respect to the normal. Air Second medium (a) Suppose that the second medium is polystyrene. What is the angle of refraction, 8, (in degrees)? (Enter your answer to at least one decimal place.) (b) Suppose that the second medium is sodium chloride. What is the angle of refraction, 8,, in this case (in degrees)? (Enter your answer to at least one decimal place.) (c) Finally, suppose that the second medium is glycerine. What is the angle of refraction, 0,, in this case (in degrees)? (Enter your answer to at least one decimal place.)A beam of light both reflects and refracts at the surface between air and glass as shown in the figure below. If the refractive index of the glass is na, find the angle of incidence 0, in the air that would result in the reflected ray and the refracted ray being perpendicular to each other. (Use the following as necessary: n.:) 0, ng 0,Question #1: Two plane mirrors are place perpendicular to each other. A laser hits mirror M1 30cm above the origin (0,0) as shown in the figure below. a) Find the distance from the origin where the laser will incident at mirror M2. b) How long it will take the laser to travel (in nano-second) from mirror M2 to the screen(situated 50 cm parallel to M1)?

- Using the figure below, find the angles of refraction for a light ray passing from air into glass with the following angles of incidence: 5°, 10°, and 20°. 45 40 35 30 25 20 15 10 10 20 30 40 50 60 70 80 90 Angle in air (*) O10° %3D 020° Do you notice a trend in the resulting values? If so, describe it. O Doubling the angle of incidence approximately halves the angle of refraction. O Doubling the angle of incidence approximately doubles the angle of refraction. O Doubling the angle of incidence approximately quadruples the angle of refraction. There is no trend in the resulting values. Based on your observations, what would you predict the angle of refraction to be for an angle of incidence of 40°? How does your value compare with that inferred from the figure?
