In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
If one considers reflective indicies, if the reflective index of the second medium (n2) is larger than the first (n1), the ray bends towards the normal. This means that n2 > n1Since n is defined as c/v, we know that the speed of light is greater in the first medium. Thus, when light changes speed from fast to slow, it bends towards the normal.
Refraction occurs because waves move at different speeds in different bodies. Because a wave hits the other medium at an angle, part of the wave changes speed earlier than the rest, turning the waves. this is most obvious with light waves in water, but it happens with all types of waves in any change of medium.
There are rarer fossils, as in fossils that belong to creatures that haven't been discovered yet or are very uncommon, but no "best" fossil.
its common. They are avalible in stores everywhere.
If the light travels faster in the second medium, then this medium is called the 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 email@example.com
It slowed down.

Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
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.

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.
