When a ray of light falls on a surface of a prism, it deviates from its original path and the ray of light is broken up into seven colours. It is the constituent color of light. Due to this a spectrum is formed. The individual colour that is visible in the spectrum , starting from…

Q 1.If the refractive index of water for light going from air to water be 1.33 , what will be the refractive index for light going from water to air Solution: We know the relation of refractive index for the two set of media.Here air is the first medium and water is second medium. For…

Refractive Index of Medium 1 to Medium 2 :Refractive index for ray of light going from medium 1 to medium 2 is equal to the reciprocal of the refractive index for ray of light going from medium 2 to medium 1. This can be proved in following way: Suppose in first case ray of light…

There are two laws of refraction of light. these are : a) Incident say , refracted ray and normal lie on same plane . The concept of plane is shown in the image. In terms of x,y and z co-ordinate system , the y-z plane is shown in light sky blue colour. We write on…

There are many effects of the refraction of life in our day to day life. For example I am citing few of them.a) The partly immersed stick appear to be bend at the surface of the water. b) The coin kept in water appears raised upward.c)The water of a pool appear less depth.d)Stars appear to…

Case1: When ray of light travels from rarer medium like air to a denser medium like glass then it bends towards normal. Case 2: When ray of light travels from denser medium like glass to a rarer medium like air then it bends away from the normal. Case 3: When ray of light travels from…

Cause of Refraction : The speed of the light in different transparent substances is different. For example speed of light in air is 3×10⁸ m/s and that of in glass is 2×10⁸ m/s. It is clear that the two speeds of the light are different. When light enters from air to glass the speed of…

Refract means bending. The bending of ray of light when it pass from one medium to another medium is known by a term called refraction. Refraction of Light happens due to different speed of light in different medium. Speed of light in air is 3×10⁸m/s and that of in glass is 2×10⁸m/s. Refraction of Light:…
