w9-10 A diamond in air is illuminated with white light. On one particular facet, the angle of incidence is 25.70°. Inside the diamond, red light (λ = 660.0 nm in vacuum) is refracted at 10.88° with respect to the normal; blue light (λ = 470.0 nm in vacuum) is refracted at 10.13°.  How would a diamond look if there were no dispersion? a. The diamond would look white.   b. The diamond would look red.   c. The diamond would look blue.   d. The diamond would be clear.

A 3.87 m long pole stands vertically in a lake having a depth of 2.07 m. When the Sun is 38.2o above the horizontal, determine the length of the pole's shadow on the bottom of the lake. Take the index of refraction for water to be 1.33.

5. A narrow beam of composite red and violet light initially in air is incident upon a rectangular block. The indices of refraction regarding the block are; n=1.50 for the red light n=1.54 for the violet light. a. If the incident beam strikes the surface of the block at an angle of a = 65.0°, what it the angular separation of the red and violet light as it exits the block, going back into air? b. Between what two angles of incidence a will only one of the colors of light emerge through the top of the block? State which color makes it through (Red or Violet).

Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm. Use na = 1.00 for the index of refraction of air. = If light incident on the glass makes an angle of = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room. Ax = 42.36 Incorrect glass air glass mm

1. A flashlight held 1.3 m above the surface of a water tank shines a beam of light on the water (index of refraction n 1.33). The light hits the water 2.7 m away from the edge of the tank, where the flashlight is held. The water tank is 2.1 m deep. (a) What is the incident angle relative to the normal? (b) What is the transmitted angle relative to the normal? (c) Where does the light ray hit the bottom of the water tank, mea- sured from the edge of the tank where the flashlight is held? light ray 2.7 m d=? = water tank 1.3 m 2.1 m
