ASK YOUR TEACHER PRACTICE ANOTHER When you stand in shallow water and look at an object below the surface of the water, the object will look farther away from you than it really is. This is because when light rays pass between air and water, the water refracts, or bends, the light rays. The index of refraction for water is 1.333. This is the ratio of the sine of 01 and the sine of 92 (see gure). (D (a) While standing in water that is 2 feet deep, you look at a rock at angle 91 = 70 (measured from a line perpendicular to the surface of the water). Find 92 in degrees. (Round your answer to one decimal place.) (b) Find the distances x and y, in feet. (Round your answers to two decimal places.) (c) Find the distance d (in ft) between where the rock is and where it appears to be. (Round your answer to two decimal places.) .'

(Round your answer to two decimal places.) d=:lft (d) What happens to d as you move closer to the rock? Explain. 0 As you move closer to the rock, d must get smaller and smaller. The angles 91 and 02 will decrease along with the distance y, so d will decrease. 0 As you move closer to the rock, d must get larger and larger. The angles 91 and 92 will increase along with the distance y, so (1 will increase. 0 As you move closer to the rock, 11 must get larger and larger. The angles 91 and 92 will decrease as the distance y increases, so d will increase. 0 As you move closer to the rock, d must get smaller and smaller. The angles 91 and 02 will increase as the distance y decreases, so d will decrease. 0 As you move closer to the rock, 11 does not change. The angles 91 and 92 will remain the same along with the distance y, so d will also remain the same. lasigowemeA
