Light travels from one optical medium to another. State the conditions necessary for total internal reflection to occur at the boundary between the two media.

One of the world's largest aquaria is the Monterey Bay Aquarium. The viewing wall is made of acrylic and is 0.33 m thick, and the tank holds 1.2 million gallons of water. A ray of light is directed into the plastic from air at an angle of a = 75°.The indices of refraction for air, acrylic, and seawater are listed on the figure. Air Acrylic Seawater 1.00 1.50 1.37 ਅਰ 1) Calculate the angle that the ray will make when it enters the plastic. (Express your answer to three significant figures.) Submit 2) Calculate the angle that the ray will make when it enters the seawater. (Express your answer to three significant figures.) Submit

Answer the following questions A. The critical angle for total internal reflection at a diamond-air interface is 25 degrees. Suppose the light falls at an angle to the normal. Then, total internal reflection will occur if the incident medium is: a) air and angle < 25 degrees b) air and angle > 25 degrees c) air and angle = 25 degrees d) diameter and angle > 25 degrees e) diamond and angle < 25 degrees B. A ray of light in water (index n1) hits its surface (with air) at a critical angle for total internal reflection. Now some oil (index n2) floats in the water. The angle between the ray in the oil and the normal is: note: sin -1 (1.00), it is read as the inverse sine of one. a) sin -1 (1/n1) b) sin -1 (1/n2) c) sin -1 (1.00) d) sin -1 (n1/n2) e) sin -1 (n2/n1) C. A ray of light passes obliquely (non-zero angle) through a glass plate that has parallel faces. The emerging ray: a) it leans more towards the normal than the incident ray b) is reflected internally toatl c) tilts…

Optical fibers are a central part of technology for rapid information transmission with a high level of efficiency. A new type of optical fiber is crafted with an index of refraction n = less than that of water in the vicinity of room temperature, where NH2O fact that n < nH20 potentially problematic if the fiber should be submerged? 1.25 = 1.33. Why is the O A. Total internal reflection would be frustrated, allowing loss of signal. O B. Internal reflection would actually be enhanced, so there is no problem. C. Electric eels might have free internet access.

Is Light Reflected or Refracted? When light propagates through two adjacent materials that have different optical properties, some interesting phenomena occur at the interface separating the two materials. For example, consider a ray of light that travels from air into the water of a lake. As the ray strikes the air-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 light in the material. It is defined as the ratio of the speed of light e in vacuum to the speed in the material, or n = { Figure incident ray interface. €₂ reflected ray refracted ▾ When light…

What is the critical angle for total internal reflection for glass in air? Assume that nglass= 1.50 and nair = 1.00.

true or false? The critical angle for a material is the angle at which all light striking at that angle or greater will experience total internal reflection.

You are using a transparent tube as an optical fiber in open air (n air=1.00) you have calculated that the critical angle for the fiber is 34.5. a) what is the index of refraction of your optical fiber? b)to make your fiber more durable, you encase it in a cladding with an index of refraction equal to 1.35. Will the beam be reflected into the fiber or will it leak into the cladding when the incident angle inside the fiber is 50.

a. A ray of light enters a fiber optic cable with index of refraction n from air at an angle e as shown below. Let the angle 0 be 69°. For total internal reflection to occur at the cable-air interface, what must be the value of n? Dair - 1 n = Ꮎ θα ec n

A ray of white light strikes the surface of a 4.0-cm-thick slab of flint glass as shown. As the ray enters the glass, it is dispersed into its constituent colors. Estimate how far apart the rays of deepest red and deepest violet light are as they exit the bottom surface. Which exiting ray is closer to point P?
