∙ 12y agoIf light goes normally to the plane of separation of the two media nothing happens in its direction.
But if it falls at angle of inclination then its direction is changed and so that phenomenon is named as refraction.
This is mainly due to the change in the speed of light. The speed of light will be less in the medium of larger refractive index. Hence the speed of light will be less in glass than in air.
This change is speed will be in different degree for different constituent colours of white light. Hence dispersion phenomenon becomes possible in case of refraction through prism.

∙ 14y agoRefraction of light happens when light rays bend due to change of medium...bascically it depends on the density of the medium....the denser the medium the more the refraction...
Refractive index measures the amount of defelection in a medium. it is the ration of light in air to that of d given medium...
Example : when you put a pencil in a glass of water it appears broken or bent at the intersection of air and water..

Is it possible to achieve total internal reflection if the object is in rarer medium?
First we should know what will be happen when the light ray goes from denser medium to rarer medium and rarer medium to denser mdeium.... 1. The light refracted away from the normal (Denser to Rarer) 2. The light refracted towards the normal (Rarer to denser) So it is not possibel to get total internal reflection whan the light travel from rarer to denser medium...... Conditions to achieve to get TIR 1. The light should travel from denser mediumt to rarer medium 2. The angle of incidence at the interface should be greater than critical angle if you are not satisfied kindly mail me cramkum@gmail.com
Why does velocity of light in rarer medium than in denser medium?
Light travels from a denser medium to a rarer medium because you did not close your curtains. It then passed through the denser window glass into the rarer air outside. The people outside the house saw you running your finger around the bottom of the cake getting a little of the icing.
What is the diffraction of light waves?
Diffraction of light waves is caused by the density of the medium through which the light is passing. Diffraction results when light travels from rarer to denser medium.
When light travels from a denser medium to a rarer medium it bends away from the normal Is it possible for the light ray to reflect back in the same medium?
Yes, at the critical angle, all of the light will reflect, and will not leave the medium.
What are the non ohmic materials give examples?
draw the ray diagram of refraction of light at curved surfaces the following rarer medium to denser medium

What happenend light from rarer to denser medium?
It slowed down.

How do light refract?
when light travels from rarer medium(which has relatively lower density) to a denser medium(which is of relatively higher density) the angle of incident light and refracted light is less than 180 degree(when the angle is considered at the point of incidence) and when the light travels from a denser to a rarer medium the angle will be greater than 180 degree.
What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
What is the diffraction of light waves?
Diffraction of light waves is caused by the density of the medium through which the light is passing. Diffraction results when light travels from rarer to denser medium.

Yes, at the critical angle, all of the light will reflect, and will not leave the medium.
Why frequency of light is not change When it enter from a rarer medium to denser medium?
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
What are the non ohmic materials give examples?
draw the ray diagram of refraction of light at curved surfaces the following rarer medium to denser medium
What is difference between rarer and danser medium?
In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
What is a rarer medium?
If the light travels faster in the second medium, then this medium is called the rarer medium.
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
NO
