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.
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
Yes, when light travels from a denser medium to a rarer medium and strikes the interface at an angle greater than the critical angle, total internal reflection can occur. In this case, the light ray reflects back into the denser medium instead of refracting into the rarer medium.
When light travels from an optically denser medium to an optically rarer medium, it bends away from the normal (angle of incidence is greater than angle of refraction) due to the decrease in the speed of light in the rarer medium. This phenomenon is known as refraction.
When light enters a denser medium from a rarer medium, it slows down, causing it to bend towards the normal. As the light exits the denser medium into the rarer medium, it speeds up and bends away from the normal. This change in speed and direction is why refraction occurs in a prism.
When a ray of light passes from an optically denser medium to a rarer medium, it bends away from the normal. This phenomenon is known as refraction. The speed of light changes as it moves from one medium to another, causing the change in direction.

It slowed down.

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.
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
When a ray of light passes from an optically denser medium to a rarer medium, it bends away from the normal. This phenomenon is known as refraction. The speed of light changes as it moves from one medium to another, causing the change in direction.
When light passes perpendicularly from a rarer medium to a denser medium, there is no change in the speed of light. Since refraction occurs due to the change in speed, the absence of speed change in this case results in no bending of the light ray.
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
If the angle of incidence is made smaller for light passing from a rarer to a denser medium, the angle of refraction will also decrease. This is because of the law of refraction, which states that light bends towards the normal when moving from a rarer medium to a denser medium. Therefore, as the angle of incidence decreases, the angle of refraction will also decrease.
When a ray of light passes from a rarer medium to a rarer medium, it will continue in a straight line and its speed will remain constant. There will be no change in the direction of the light ray.
