Bella and Asante now work a problem to determine whether they understand total internal reflection. A thin film of water sits on top of a flat piece of glass. Note that n water = 1.333 and n glass = 1.56. For total internal reflection, does Asante say the light starts in the glass or in the water? "In the water, because the water has a higher index of refraction" "In the glass, because the glass has a lower index of refraction" "In the glass, because the glass has a higher index of refraction" "In the water, because the water has a lower index of refraction" Asante is correct. Total internal reflection can occur only when light travels from a region of higher to lower index of refraction. What is the critical angle for which total internal reflection will occur?
A beam of light travelling through glass meets the interface with air at an incidence angle of i = 30° and is refracted at an angle r = 45°. At what angle does total internal reflection occur for this interface? angle =

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…
