The normal in refraction is an imaginary line perpendicular to the surface where the light ray enters. It helps determine the angle of incidence and angle of refraction, and is used in Snell's Law to calculate how the light ray will bend when passing through different mediums.
The angle of refraction is measured between the refracted ray and the normal line (perpendicular line) to the surface of the material at the point of incidence.
In the context of refraction, "normal" refers to an imaginary line perpendicular to the surface at the point where the light ray hits. It is used as a reference point to determine angles of incidence and refraction. The concept of "normal" remains the same in this context as it is used in optics to describe the behavior of light waves.
No, a wave does not refract when it enters a medium along the normal line. Refraction occurs when a wave enters a new medium at an angle, causing it to change speed and change direction. If the wave enters the medium along the normal line, it will continue in the same direction with no refraction.
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
The angle between the refracted ray and the normal is called the angle of refraction. It is measured from the normal to the refracted ray inside a medium due to the bending of light as it passes through different mediums.
The angle of refraction is measured between the refracted ray and the normal line (perpendicular line) to the surface of the material at the point of incidence.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
The light will bend towards the normal to the surface at the boundary between the two materials. This is known as refraction.

Refraction
It is normal refraction of the moonlight in ice crystals which are in high layers of clouds.
The angle between the refracted ray and the normal is called the angle of refraction. It is measured from the normal to the refracted ray inside a medium due to the bending of light as it passes through different mediums.
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
Angle of refraction will be less compared to the angle of incidence in this case.
