After a long day of driving you take a late-night swim in a motel swimming pool. When you go to your room, you realize that you have lost your room key in the pool. You borrow a powerful flashlight and walk around the pool, shining the light into it. The light shines on the key, which is lying on the bottom of the pool, when the flashlight is held 1.2 m above the water surface and is directed at the surface a horizontal distance of 1.5 m from the edge. If the water here is 4.0 m deep, how far is the key from the edge of the pool? (Given refractive index of water is = 1.33) 1.5 m 1.2 m 4.0 m

Light takes the path that allows it to travel from point A to point B in the shortestpossible time. You are lost something on the bottom of a pool at night. The water is4.0 m deep. You search for it. You are holding a light source 1.2 m above the watersurface. When the light reaches the object on the bottom of the pool it is directedsuch that it crosses the water surface at a distance of 1.5 m from the edge (see Figure).The index of refraction of water is nH2O = 1.33, while the index of refraction of air isnair = 1.00.Calculate the distance of the object from the edge of the pool.

After a long day of travel, late at night, you swim in the pool of the hotel where you are staying. As you retire to your room, you realize you have lost the key to the pool. You get a powerful flashlight and walk around the pool shining the light on it. The light illuminates the key, which lies at the bottom of the pool, when you hold the flashlight 1.2 m from the surface of the water and point it toward the surface at a horizontal distance of 1.5 m from the edge (see figure). If the water at that point is 4.0 m deep, how far from the edge of the pool is the key?

8. In searching the bottom of a pool at night, a watchman shines a narrow beam of light from his flashlight 125 cm above the water level to a point 195 cm from his foot at the edge of the pool. Where does the spot of light hit the bottom of the pool, relative to the edge, if the pool is 215 cm deep? beam of ight 125 EIS m a. 175.8 cm b. 370.8 сm с. 70 ст d. 215 cm e.

A submarine on a spy mission is 107.5m horizontally out from the shore and 211.8m beneath the surface of the sea water (n=1.48). A laser beam is sent from the sub and strikes the surface of the water close to the shore. The refracted light leaves the water and strikes the roof of a hotel 138.8m from the shore. How tall is the hotel in meters?
At night, a person (in air) stands, at the edge of a water-filled swimming pool with a flashlight in hand, looking down at an angle into the pool for a set of car keys (he/she) dropped accidentally to the bottom of the pool earlier in the day. The flashlight is adjusted until the keys can be seen. The vertical distance from the flashlight to the water is 1.5m. The horizontal distance from the flashlight to the point at which the light beam enters the water is 1.7m. The pool is 5m deep. What is the horizontal distance, measured from the from the edge of the pool, starting at the bottom, to the keys? Consider the index of refraction for both air and water in your calculations.
