5. Unpolarized light from the Sun reflects from the surface of water (n = 1.33). At what angle of incidence (relative to the normal) does the reflected light become completely polarized? Draw this scenario and indicate the direction of polarization of the reflected ray (remember you can use a O, or an® to represent polarization perpendicular to the page). 6. Red laser light enters a fiber optic cable (left edge) at an angle @(measured from the normal) and propagates down...
Question: In this problem you will be considering Brewster's angle. Light travelling through a medium with refractive index ni = 1.09 is incident at an angle lº to the normal on a medium with refractive index n2 = 1.45. A n2 Figure 1. Polarised light travelling through a medium with refractive index ny is incident at an angle 0 (to the normal) on a block with refractive index n2. Part 1) What is Brewster's angle OB in this case? OB=...
6. (2 pts.) Suppose that sunlight strikes the flat horizontal surface of a car hood that is coated with a transparent layer of car wax (n = 1.54). At what angle of reflection is the reflected light completely (100%) horizontally polarized? Show your work. Thought question (not for credit]: In order to block as much of the reflected sunlight as possible from reaching your eyes, you should wear polarized sunglasses that have polarizers with what orientation?
2. A block of plastic with refractive index np-1.68 is immersed in oil (no-1.516). Randomly polarized light (ie, 50% s-polarization and 50% p-polarization) is incident from the oil towards the plastic at an angle of 65" to the normal. a) What percentage of the p-polarized component of the light is reflected off the plastic? b) What percentage of the total incident power of the light is transmitted into the block? c) What is the ratio of the s-polarized reflected power...
6. a. (4) Unpolarized light of intensity 100w/m? at point "A" traveling through air (index one) en- counters a planar junction with plastic of index of refraction 1.4 at an angle θ such that the reflected light is completely plane-polarized. What is the numerical value of θ? b. (4) What is the polarization unit vector of the reflected light at "B"? Circle the vector on the figure and give a formula for it in terms of i,j,k and anything else...
Project (2) Read the manual When unpolarized light is incident on the surface of (say) glass at the Brewster angle, the reflected light is polarized with its polarization parallel to the surface of the glass. The Brewster angle is given by Tan(O) = n where n is the refractive index of glass. The material need not be glass; it could be plastic, water etc. (any smooth transparent material is fine). Exercise: (1) The Brewster angle in the experiment is found...
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...
#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...
An aquarium filled with water (n = 1.33) has flat glass sides whose index of refraction is 1.55. A beam of light from outside the aquarium strikes the glass at a 43.5∘ angle to the perpendicular (Figure 1).A) What is the angle of this light ray when it enters the glass?B) What is the angle of this light ray when it enters the water?
The index of refraction for red light in water is 1.331 and that for blue light is 1.340. If a ray of white light enters the water at an angle of incidence of 61.55o, what are the underwater angles of refraction for the blue and red components of the light? (Enter your answers to at least two decimal places.) (a) blue component (b) red component Need Help? Read It The light beam shown in the figure below makes an angle...
