   Index of refraction. Light travels at a speed c = 3 x 108 m/s in a vacuum. In a transparent medium, light travels slower than in a vacuum. The index of refraction of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in the medium.

   Q25.16 A mirage occurs when light changes direction as it moves between batches of air having different indices of refraction because they have different densities at different temperatures. When the sun makes a blacktop road hot, an apparent wet spot is bright due to refraction of light from the bright sky.

   In this Chapter, we shall study the phenomena of reflection and refraction of light using the straight-line propagation of light. These basic concepts will help us in the study of some of the optical phenomena in nature.

   In the case where a traveling ray of light does encounter an obstacle while traveling in a medium the light often undergoes two processes – reflection and refraction. Some percentage of the light will reflect from the surface of the obstacle and the remaining light will transmit into the material, or refract.

   The Refraction of Light: Lenses and Optical Instruments. 1. “Refraction” refers both to (1) the crossing of light from one medium to another medium with. different refractive index, and (2) the change of direction that occurs on crossing the boundary.

   In this chapter we will study the phenomena of reflection and refraction using the property of light i.e. straight line propagation (Light wave travel from one point to another, along a straight line). Reflection of Light. When the light is allowed to fall on highly polished surface, such as mirror, most of the light gets reflected.

   What is the law of refraction?

   • Figure 1 In the law of refraction, a ray of light that is incident on a surface can, again, be said to be traveling with some angle of incidence to the surface. Here, the surface acts as a boundary between two media. Within each medium the speed of light is different.

   What is the index of refraction?

   • The index of refraction is equal to the ratio of the speed of light in a vacuum to the speed of light in that medium (Eq. 2). (Eq. 2) Because of the speed difference between the two media, as a light ray crosses the boundary and is transmitted into the next medium, the direction the ray is traveling will change.

   What is Snell's law of refraction?

   • From this equation we see that the direction in which the light is bent depends on whether it is going from a slower to a faster medium or vice versa. This equation is known as Snell’s law of refraction. The index of refraction of a glass is n = 1.6. A ray of light is incident upon the glass surface at an angle of 30o.

   When light goes from one material into one having a higher index of refraction, it refracts toward the normal line of the boundary between the two materials. If, as the light travels through the new material, the index of refraction continues to increase, the light ray will refract more and more toward the normal line.
