A tank whose bottom is a mirror is filled with water to a depth of 20.6 cm . A small fish floats motionless 7.80 cm under the surface of the water. Part A What is the apparent depth of the fish when viewed at normal incidence to the water? Express your answer in centimeters. Use 1.33 for the index of refraction of water. Part B What is the apparent depth of the reflection of the fish in the bottom of...

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...

You kneel beside a fish tank (containing alcohol for unknown
reason) and surprisingly found a fish there. You see it by sunlight
that reflects off the fish and refracts at the alcohol-air
interface as shown in the figure below. What is the angle of
refraction (in degrees) if this transparent alcohol has index of
refraction given by 1.38?
A. 43.6
B. 39.9
C. 45.2
D. 41.1

A tall cup of diameter D is partially filled with a liquid with the refraction index n to a height of H_water. A student looks downward just over the left rim of the cup at an angle theta with the water's surface. At this angle, the refraction of light at the water's surface just barely allows her to see the bottom-right corner of the cup. A sketch of the path of light is shown at the right. Derive the formula...

#3 Suppose you have a fish tank made of a plastic polymer that has a mirror on the bottom. The fish tank is exactly half full of water. The fish tank is lit by a light coming from the upper, left hand corner, which you can approximate as a ray of light traveling at 45 degrees from the normal towards the water. For fun you put a mirror on the top of the tank as well. A) Draw the transmitted...

1 A horizontal cylindrical tank 2.20 m in diameter is half full of water. The space above the water is filled with a pressurized gas of unknown refractive index. A small laser can move along the curved bottom of the water and aims a light beam toward the center of the water sur- face (Fig1). You observe that when the laser has moved a distance S = 1.09m or more (rneasured along the curved surface) from the low- est point...

U Question 21 20 pts Light enters the curved surface of a semicircular block filled with an unknown liquid. This block is surrounded by air. The incident angle is 25.0°. A screen is 3.20 cm away, and the refracted light strikes the screen 2.80 cm above the normal. What is the index of refraction? At what angle would the light ray be totally internally reflected? You may find a drawing of the situation helpful. Upload Choose a File D Question...
