A light guide is a device used to direct light from a light source (commonly an LED) to a place where the light is needed. Light guides are also sometimes referred to as light pipes. Light guides are usually mad

If the speed of light in a medium is 2.5×108 m/s , its absolute refraction index ≅……….. View Solution Speed of light in glass is 2×108ms−1. What is the refractive index of glass ? View Solution Speed of light in glass is 2×108m/s. Refractive index of glass is... ...
The index of refraction of a glass plate is 1.53. What is the Brewster's angle when the plate is in the air? Water?Brewster's Law and Brewster's Angle :When unpolarized light traveling from one medium to another transparent medium is inciden...
To find the refractive index of water when the refractive index of glass with respect to water is given as 1.125 and the refractive index of glass is 1.5, we can use the formula for the refractive index:
Next two letters indicate one or two of the main ingredients e.g. S-LAH51 has lanthanum as its main ingredient while S-BSL7 (Ohara's equivalent to BK7) is a boro (B) silicate (S) glass. Confusingly these letters may or may not match the symbols for those chemical elements e.g. ...
4 A student is investigating refraction of light.(a)What is refraction?(b)The diagram shows a ray of light travelling from air to glass.Add labels to show the angle of incidence, i, and the angle of refraction, r.normal/air glass(c)The student wants to find the refractive index of th...
Diamonds have a higher index of refraction than water, which is to say that those sparkly, costly light traps slow down light to a greater degree. Lenses, like those in a telescope or in a pair of glasses, take advantage of refraction. A lens is a piece of glass or other transparent ...
In physics, we say the glass has a higher refractive index for blue light than red light. What color is least bent? Since violet light has a shorter wavelength, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while red light is ...
