- An optical coating with an index of refraction of 1.23 is applied to glass with an index of refraction of 1.50. If the thickness of this coating is 184nm, what wavelength(s) of visible light in air are most strongly reflected from this surface? Visible wavelengths range from 350nm to 700nm.A small lamp is 5.0 m below the surface of a lake. It emits light in all directions. A boat goes from directly over the lamp to the first point where the lamp can no longer be seen. How far, in m, does the boat travel? Take the refractive index of water to be 1.30 and the refractive index of air to be the same as that of a vacuum. O 6.0 11 50 O 1.2 O 21 8.3Jackson is standing in air and is shining a flashlight at a 62-cm-thick slab of glass. His beam makes an angle of 83.5 degrees with the surface of the glass. The glass is a dispersive medium, and has an index of refraction of 2.1 for red light and 2.3 for purple light. Find the distance between the point where the red light leaves the slab and where the purple light leaves it. [The angles of refraction are small, so make the appropriate approximation when calculating their sines.]
- 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 tumor14. The figure shows a ray of light that passes from the white material A (with index of refraction nA = 1.1) into the grey material B. (a) In which material does the light travel faster? A) Material A B) Material B (b) What is the index of refraction of material B? 30° 60° A 70° B 20°Laser light is passed through a rod made out of a material with an index of refraction of 1.62, a length L = 45.0 cm, and square cross section of length h = 3.00 mm on a side as shown in the figure. If the light enters at the center of the rod with an angle of incidence in air of 0₁ = 49.7°, determine the number of total internal reflections before it emerges from the opposite end of the rod. 42.0 cm 3.10 mm
- Lunar astronauts placed a reflector on the Moon’s surface, from which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. What percent error is this, given the average distance to the Moon is 3.84 × 108 m?A coating is being applied to reduce the reflectivity of a pane of glass to light with a frequency of 4.14 × 10¹4 Hz that is incident normally on the pane. If the material has an index of refraction of 1.34 and the glass has an index of refraction of 1.537, what is the minimum thickness the coating should have in nanometers? Please keep one decimal place in your answer. (c = 3.00 × 108 m/s)Fiber optic cables, such as those used for high-speed communication (Internet & phone services), transmit signals as light pulses through transparent cables. When viewed from one of the ends, you can see these light pulses, but when viewed from the side you can't. Using your knowledge about reflection and refraction, explain how this might work. Is there some physical limitation where this might not work?
