A film of oil, with an index of refraction of 1.52 and a thickness of 1.50 cm, floats on a pool of water, as shown in the figure. (see figure). A beam of light is incident on the oil at an angle of 60.0 degrees to the vertical. A) Find the angle θ the light beam makes with the vertical as it travels through the water. B) How does your answer to part A depend on the thickness of the oil film? Explain

A flat sheet of ice (n = 1.309) has a thickness of 2.7 cm. It is on top of a flat sheet of crystalline quartz (n = 1.544) that has a thickness of 1.5 cm. Light strikes the ice perpendicularly and travels through it and then through the quartz. In the time it takes the light to travel through the two sheets, how far (in cm) would it have traveled in a vacuum? Number i Units

In order to identify an unknown material you are asked to solve for the critical angle of the material. In order to test this you set up a beam of light that strikes the unknown substance from air (n = 1.0) at an angle of 30° with respect to the normal.  It continues on in the substance at an angle of 23° with respect to the normal.  What is the critical angle for the unknown substance?     51°     55°     60°     63°

As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction 82 for the light in the olive oil is 34.8°, determine the angle of incidence e, in air and the angle of refraction e3 in water. The index of refraction for olive oil is 1.47. 83 = air oil water

Use the exact values you enter to make later calculations.A ray of light strikes a flat, 2.00-cm-thick block of glass (n = 1.96) at an angle of ? = 32.4° with respect to the normal (see figure below). A light ray incident on a glass block of thickness 2.00 cm is shown. The ray travels down and to the right and is incident to the top of the block at an angle ? to the normal of the surface. The ray inside the block moves down and to the right but at a steeper slope than the incident ray. It is incident on the bottom surface of the block and exits moving down and to the right, in the same direction as the incident ray. A dashed line extends from the original path of the ray down in the block and is shown to be a distance d from the ray that exits the glass block. (a) Find the angle of refraction at the top surface and the angle of incidence at the bottom surface. °(b) Find the refracted angle at the bottom surface. °(c) Find the lateral distance d by which the light beam is shifted. cm(d)…

A beam of light is incident on a square piece of glass with side s =  10.0 cm and index of refraction 1.50. The angles are shown in the figure to scale (you can count the blocks to measure them if you don't have a protractor). Where does the beam exit the glass? Assume the glass is in air (n = 1.00).
