• ## 8. Relation between Angle of Incident Emergent Angel Angle fo Deviation and Angle of Prism Physic

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…

• ## 7.Sum of Refractive Index Physics Class 10

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…

• ## 6.Refreactive Indext of Light From Medium 1 to Medium 2 and Vice Versa Relation

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…

• ## 5. Law of Refraction Of Light Physics Class 10

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…

• ## 4. Effects of Refraction of Light Physics Class 10

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…

• ## 3 Three Cases of Refraction of Light Physics Class 10

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…

• ## 2. Causes Of Refraction of Light Physics Class 10

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…

• ## 1 Refraction of Light Definition and Introduction Physics Class 10

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:…
