Immiscible liquids (ones that do not mix) can be placed on top of each other in a glass. Each layer may have a different refractive index. PING PONG BALL LAMP OIL RUBBING ALCOHOL SODA CAP BEADS VEGETABLE OIL WATER CHERRY TOMATO DISH SOAP If we shine a ray down from the air above into the glass on the left at an angle of 3.8 degrees from the vertical, what is the angle of the light when it reaches the bottom of the glass? (Units: degrees) n (air) 1.00 n (lamp oil) 1.51 n (rubbing alcohol) n (vegetable oil) n (water) n (dish soap) 1.39 1.45 1.33 1.35

A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction?   Calculate to 1decimal.

A beam of light is pointed at the surface of a block of crown glass at an angle of 40.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). Part of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted beams?

A thin beam of light makes an angle of 60° with the surface (not the normal) of a body of water (n = 1.33). Once the light beam refracts into the water what angle does the beam make with the surface of water?     30°     68°     22°     60°

A light ray in air (n = 1.00) hits turpentine (n = 1.47) at an angle of 35° to the surface. Determine the angle of refraction.

The figure below shows the path of a beam of light through several layers with different indices of refraction. (Assume n. 1.08.) n = 1.60 n = 1.40 n = 1.20 (a) If 01 36.0°, what is the angle 0, of the emerging beam? %D (b) What is the smallest incident angle 0, to have total internal reflection at the surface between the medium with n = 1.20 and the medium withn, = 1.08?

A ray of light crosses the boundary between some substance with n = 1.61 and air, going from the substance into air. If the angle of incidence is 18◦ what is the angle of refraction?   Calculate to 1decimal.

Consider a layer of Oil, Glass, and Air where the oil/glass boundary is parallel to the glass/air boundary. Let the index of refraction for the glass be 1.48 and the index of refraction for the oil to be 1.25. At what angle relative to the normal should a ray of light be directed upon the oil/glass interface such that it strikes the glass/air interface at the critical angle?

A certain kind of glass has an index of refraction of 1.660 for blue light of wavelength 420 nm and an index of 1.620 for red light of wavelength 690 nm. If a beam containing these two colors is incident at an angle of 30.0° on a piece of this glass, what is the angle between the two beams inside the glass?

A laser beam is incident on the surface of a block of crown glass at an angle of 34.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). Part of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted beams?
