Rays of the Sun are seen to make a 36.0° angle to thevertical beneath the water. At what angle above the horizonis the Sun?

(a) A light ray is incident on the left side of the prism shown in the figure below. The prism is a right triangle, with two of its angles measuring 45°. The transmitted ray that exts the hypotenuse of the prism makes an angle of 0- 17.4" with the direction of the incident beam. What is the index of refraction of the prism? (Round your answer to at least two decimal places) 45,0 (b) What If? In part (a), we assumed the ray was monochromatic. Consider instead the case where the ray was composed of white light. Because the index of refraction differs for differenti wavelengths, the white light would be dispersed into constituent colors. Assume the index of refraction for blue wavelengths is 1.01m and for red wavelengths it is 0.99n, where it is the index of refraction found in part (a). What is the angular spread (in degrees) between red and blue light exiting the prism? Need Help?

A fish swimming in the sea in water with an index of refraction of 1.33 observes the Sun to be 30 degrees away from the vertical. How far from the vertical (to the nearest degree, i.e. as an angle) would a fisherman sitting nearby on the deck of a boat (index of refraction of air is 1.00) see the Sun? Answer:

Light rays from the Sun, which is at an angle of 64o above the western horizon, strike the still surface of a pond. What is the angle of reflection at which the rays leave the pond’s surface?   Round your answer to 0 decimal places.

The eyes of a person standing at the edge of a 1.2-m-deep swimming pool are 1.6 m above the surface of the water.Light coming from a silver dollar at the bottom of the pool entersthe person's eyes at an angle of 37° below the horizontal. Draw a picture of a light ray that leaves the dollar and enters the person'seyes and calculate the horizontal distance from the person to the dollar.

A 4.00-m-long pole stands vertically in a freshwater lake having a depth of 2.85 m. The Sun is 42.0° above the horizontal. Determine the length of the pole's shadow on the bottom of the lake. Need Help? Watch It Read It

The Sun appears at an angle of 52.8° above the horizontal as viewed by a dolphin swimming underwater. What angle does the sunlight striking the water actually make with the horizon? (Assume nwater = 1.333. Enter an answer between 0° and 90°.)

One night while on vacation in the Caribbean you walk to the end of a dock and, for no particular reason, shine yourlaser pointer into the water. When you shine the beam of light on the water a horizontal distance of 2.4 m from thedock, you see a glint of light from a shiny object on the sandy bottom—perhaps a gold doubloon. If the pointer is1.8 m above the surface of the water, and the water is 5.5 m deep, what is the horizontal distance from the end of thedock to the shiny object?

A man shines a flashlight from a boat into the water, illuminating a rock as in the figure below. What is the angle of incidence ₁ (in degrees)? 1 3.62 ml 0₂ 2.18 m-

Current Attempt in Progress A spacecraft is in a circular orbit about the moon, 1.94 x 105 m above its surface. The speed of the spacecraft is 1570 m/s, and the radius of the moon is 1.74 x 106 m. If the moon were a smooth, reflective sphere, (a) how far below the moon's surface would the image of the spacecraft appear, and (b) what would be the apparent speed of the spacecraft's image? (Hint: both the spacecraft and its image have the same angular speed about the center of the moon.)
