A child sitting at the edge of a swimming pool sees a coin resting on the bottom of the pool.  The coin appears to be 1.8 m directly below the water's surface.  How deep is the pool at the location of the coin?  The index of refraction of water is 1.33.

A beam of light containing red (660 nm) and violet (410 nm) wavelengths travels from air, through a flat piece of crown glass 2.36 cm thick, and then back to air. (a) If the beam has an angle of incidence of 22.6° in air, determine the angle at which the two colors of light emerge from the crown glass. The index of refraction respectively for red and violet light in crown glass is 1.512 and 1.530. (Enter a number to three decimal places.) red violet (b) Determine the distance separating the red and violet light as it emerges from the glass. 8.19e-3 How does the horizontal displacement of red light as travels through the glass depend on the angle of refraction of red light into the glass and the thickness of the glass? cm

A light ray traveling in air is incident on one face of a right-angle prism with index of refraction n = 1.49, as shown in Figure P22.54, and the ray follows the path shown in the figure. Assuming that θ = 58.0° and the base of the prism is mirrored, determine the angle made by the outgoing ray with the normal to the right face of the prism.?degrees

A light ray enters a rectangular block of plastic at an angle 0, = 47.8° and emerges at an angle 0, = 73.2°, as shown in the figure below. (a) Determine the index of refraction of the plastic. (b) If the light ray enters the plastic at a point L = 50.0 cm from the bottom edge, how long does it take the light ray to travel through the plastic? ns
