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 Read more
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 Read more
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 Read more
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 Read more
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 Read more
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 Read more
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 Read more
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 Read more
