When a fisher casts his line into the water, the location where he sees the fish is not actually where the fish is, due to refracting light. Given that the index of refraction is higher in water than in air, is the horizontal distance to the fish actually farther from the fisher or closer compared to where he sees it?
Homework Answers
The horizontal distance to the fish actually closer from the fisher compared to where he sees it. This is because of the fact that when light enters from rarer medium (air) to denser medium ( water) then light ray will bend towards normal, so the horizontal distance from fish to fisher will decrease..

A fisherman spies a fish underneath the water, which appears to be at a depth d_0 of 7m. The refraction angle of the light from the fish to the fisherman theta_f is 54 degree. (a) Consider the line perpendicular to the water at the point where the light transitions from water to air. Express the distance l from this line to the fish in terms of theta_f and d_0.- What is its value? (b) Express theta_i, the angle of incidence...

Bear Grylls has asked you to provide technical/scientific support for his cable television show Man Versus Wild. This show features Bear teaching viewers survival techniques while stranded in remote locations. In one scene, Bear is demonstrating to viewers the skill of spear fishing. While standing in a shallow river, Bear spots a fish. His first reaction is to aim directly at the fish, which would mean aiming at an angle φ = 43.40o with respect to the vertical, as shown...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed 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...

Question 5:
How would dust and oil on the glass plates affect the
results?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...

1. A 67-kg base runner begins his slide into second base when he is moving at a speed of 4.5 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? (b) How far does he slide? 2. A 0.32-kg stone is held 1.4 m above the top edge of a...
