2. If a ray is incident on a block of material at 15° from the vertical, and is refracted to 8° from the vertical, what is the index of refraction?

1) What does Brewster's angle give? a. The angle for maximum resolution. b. The angle for 100% polarization upon reflection. c. The minimum angle of deviation. d. The angle for total internal reflection.

1) What is the speed of light in a glass(n=1.5)? 2) A man 1.80 m tall stands in front of a vertical plane mirror. What is the minimum height of the mirror, if he is to see his whole body? Assume his eyes are 10 cm below the top of his head.

14. The index of refraction of ethyl alcohol is 1.36. If light strikes an ethyl alcohol-air boundary at an angle of incidence of 35°, will the light refract through, or will it be totally internally reflected? Justify your response.

1. A ray of light is passing through air (n=1).  It strikes a level surface of water (n=1.33) at an angle of 40° with respect to the surface of the water.  The water is 10 cm thick.  The light ray refracts and travels through the water.  There is a level layer of clear polystyrene (n = 1.6) that the water is resting upon. The light ray hits the polystyrene level and travels through it, finally reaching a sheet of glass (n=1.45). Given that the speed of light in a vacuum is 3 x 108 m/s, calculate the speed of light in the water and the time it takes for the light to traverse the water layer.     (actual question i need answered) *Using the arrangement in Problem 1, calculate the critical angle for total internal reflection at the polystyrene-glass interface

5. Light enters a container of benzene at an angle of 43° to the normal; the refracted beam makes an angle of 27° withthe normal. Calculate the index of refraction of benzene.

6. Light is incident on a layer of water (n = 1.33) in a clear glass container (n = 1.52), as shown in the image below. air water glass = 1.00) at the critical angle, If the beam of light hits the boundary of the glass and air (n what is the angle of incidence 0? 41.1° 41.2° 48.8 61.3°

2.-A triangular glass prism with apex angle Φ = 60 has an index of refraction of n = 1.50 (see Figure 1). What is the minimum angle of incidence θ1 at which a light ray can emerge from the other side?

2. (a) A ray of light in air is incident on an air-to-glass boundary at an angle of exactly 30° with the normal. If the index of refraction of the glass is 1.65, what is the angle of the refracted ray within the glass with respect to the normal?
