Chapter 25: Q23PE (page 930)

At what minimum angle will you get total internal reflection of light traveling in water and reflected from ice?

Short Answer

Expert verified

When light travels through water and is reflected by ice, the critical angle is 79.11掳.

Step by step solution

01

Definition of angle of refraction

At the point of refraction, the angle formed by a refracted beam and a line drawn normal to the interface between two media.

02

Finding the minimum angle

Let us solve the given problem,

The expression to find the critical angle is,

胃鈭�=sin-1n2n1

Here,

  • 胃鈭�is a critical angle.
  • n1is the index of refraction of medium 1.
  • n2is the index of refraction of medium 2.

The refractive index of water is 1.333 and of ice is 1.309.

Substituting 1.333 for n1 and 1.309 for n2 to calculate the critical angle,

胃鈭�=sin-11.3091.333=79.11掳

Therefore, the crucial angle when light flows through water and is reflected by ice is79.11掳.

Suppose you are using total internal reflection to make an efficient corner reflector. If there is air outside and the incident angle is 45.0潞 , what must be the minimum index of refraction of the material from which the reflector is made?

Why is the index of refraction always greater than or equal to 1?

Does the fact that the light flash from lightning reaches you before its sound prove that the speed of light is extremely large or simply that it is greater than the speed of sound? Discuss how you could use this effect to get an estimate of the speed of light
