In the figure, a laser positioned on a ship is used to communicate with a small two-man research submarine resting on the bottom of a lake. The laser is positioned 12 mabove the surface of the water, and it strikes the water 20 m from the side of the ship.The water is 76 m deep and has an index of refraction of 1.333. If the laser reachesthe submarine, how far horizontally is the submarine from the side of the ship?12 me 20 m →76 m

After a long day of driving you take a late-night swim in a motel swimming pool. When you go to your room, you realize that you have lost your room key in the pool. You borrow a powerful flashlight and walk around the pool, shining the light into it. The light shines on the key, which is lying on the bottom of the pool, when the flashlight is held 1.2 m above the water surface and is directed at the surface a horizontal distance of 1.5 m from the edge. If the water here is 4.0 m deep, how far is the key from the edge of the pool? (Given refractive index of water is = 1.33) 1.5 m 1.2 m 4.0 m
X rays are typically used to kill off cancer cells, however an issue some radiologists run into is the damage an x-ray may do to surrounding tissue. Because of this, accuracy plays a key role in radiation therapy. Suppose you are a medical physicist, and you have been given the task of choosing a medium with a proper index of refraction to bend the x rays such that they only hit the tumor. Suppose you know that the x ray comes in at an angle of 20 degrees with respect to the normal of your second medium. You know the tumor expands out to 5 degrees on either side of the normal what is the minimum index of refraction needed for the x ray to hit the tumor
Red light is incident in air on a 30° -60° - 90 ° prism as shown. The incident beam is directed at an angle of ₁ = 40.20 with respect to the horizontal and enters the prism at a height h = 20 cm above the base.

In an optics lab, an experiment is performed using two identical lasers and two identical photodetectors. Each detector is the same fixed distance away from the emitter of each laser. Light emitted from the first laser travels only through air before reaching the detector. Light emitted from the second laser first travels through a 6.10 m long column of diamond before emerging in air and continuing to the detector. The index of refraction of diamond is 2.419. The lasers each emit a pulse of light simultaneously. What will be the difference in the times of arrival of the two pulses at the detectors (in ns)? ns
