A diver under water looks up toward the surface, where the sky
appears to
subtend a cone with vertex at the diver’s eye. (a) What is the
half-angle of the
vertex of the cone? (b) What does the diver see at angles larger
than this angle
calculated in part (a)? Use nair = 1 and nwater = . 3

You place a perfectly straight 24 cm long rod into a tray of water so that half the rod is under water. The rod makes an angle of θ = 44.3° with the surface of the water. Calculate the angle that the part of the rod underneath the water appears to make with the surface of the water. Take the index of refraction of the water to be nwater = 1.33 and the index of refraction of air to be...

QUESTION If the water is replaced by a transparent fluid with a higher index of refraction, the critical angle of the fluid- air boundary is: O smaller. o the same as for water. o larger PRACTICE IT Use the worked example above to help you solve this problem. (a) Find the critical angle for a water-air boundary if the index of refraction of water is 1.33. (b) Use the result of part (a) to predict what a fish will see...

(15) A diver has decided to go for a night dive. Unfortunately, the crew of another small dive boat has ignored the warning floater and decided to drop an anchor in the immediate vicinity. While the diver was distracted by marine life, the diver's foot was pinned under the anchor and wedged against a rock. To escape, the diver must signal an SOS to the boat above using a powerful, but narrow beam, dive light. The diver's depth gauge reads...

Constants Part A Draw a straight line on a piece of paper. Fill a transparent drinking glass with water and place it on top of the line you have drawn, making sure the line extends outward from both sides of the glass. Position your head above the glass, but not directly above, such that you look downward at an angle to see the image of the line through the water, as shown in (Figure 1). The image of the line...

B. Describe what happens at a point on the surface of the water where: • a crest meets a crest . . a trough meets a trough a crest meets a trough For each of the above cases, describe how your answer would differ if the amplitudes of the two waves were not equal. Explain your reasoning. If the waves from two identical sources travel different distances to reach a particular point, the amplitudes of the waves from...

Assume now that you mistakenly filled the tank up to the blue line in the figure below. Using your ruler and protractor, draw the reflected and refracted rays for both incoming rays and read from the figure their angles (again, the red ray is 1 and the green one is 2) ang Note: the point of incidence is now where each ray crosses the blue line. The angles from the normal lines in those two points are those calculated in...
