If the light travels faster in the second medium, then this medium is called the rarer medium.
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
The speed of light changes when it goes from one medium to another one with a different index of refraction. The angle of incidence doesn't influence the change in speed.
angle of refraction will also decrease as according to laws of refractio sin i/sin r= constant (CONSTANT IS THE REFRACTIVE INDEX OF THE MEDIUM).
Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.
It happens when light travels through a material that has a greater "optical density" (refraction index, really) than a bordering material, and when it touches the surface at an angle that is sufficiently flat.
In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
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
NO
It slowed down.

Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
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.

Yes, at the critical angle, all of the light will reflect, and will not leave the medium.
