   'He controlled, changed the focus of light rays in his eyes with his mind.' Dr. Bates performed experiments on the eyes of animals, and observed the function of animal, patient's eyes under different conditions. He used the retinoscope to see the refraction of light rays in the eye under various conditions. He proved that the

   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.

   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.

   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.

   What are the laws of refraction?

   • The laws of refraction govern the behaviour of light as they pass through the interface between two media. It is generally known as Snell’s Law. From the above-depicted activity, we can say that the refraction of light follows two laws:

   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.

   What is refraction in physics?

   • Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship

   Which ray undergoes total internal reflection?

   • (c) for θ1> θC, the incident ray undergoes total internal reflection. There is no refracted ray at all. Application of Total Internal Reflection: Optical fibers are coated with a cladding of higher refractive index than the fiber itself. The internal reflections keeps the light in the fiber even when the fiber is bent.
