When waves enter a more dense medium, they tend to bend toward the normal, or the line perpendicular to the interface. This phenomenon is known as refraction and occurs because the speed of the wave changes as it moves from one medium to another, causing it to change direction.

What happens when light goes from a less dense medium to a more dense medium?
When light goes from a less dense to a more dense medium, it slows down and changes direction. This change in speed and direction is known as refraction. Refraction occurs because the speed of light is different in different mediums, causing the light waves to bend as they enter the more dense medium.
What is the light ray when it enter or exits a water air at an angle of 15 degrees with the normal?
When light enters or exits water into air at an angle of 15 degrees with the normal, the light ray will refract, or bend, away from the normal. This is because water is optically denser than air, causing the light to bend towards the less dense medium.
Why light bends away from normal when enter from denser to rare medium?
Light slows down when it enters a denser medium due to increased interactions with the molecules in the medium. This slowing causes the light waves to bend away from the normal line to maintain the same frequency and to obey the law of conservation of energy.
When light rays enter a medium at an angle they?
undergo refraction, where the speed and direction of the light rays change due to the change in the medium's optical density. This bending of light rays is due to a change in the velocity of light as it travels from one medium to another.
What happens to a ray of light that slows down when it hits a new medium at an angle?
When a ray of light slows down as it enters a new medium at an angle, it also changes direction. This change in speed and direction is called refraction. The amount by which the light bends depends on the difference in the speed of light between the two media.

When light rays enter a new medium at an angle what does the change in speed cause the ray to do?
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.
Why does the light bent toward normal when enter from air to glass even if it reduce speed but why bent?
i think the answer is that {it is my own thinking answer} when light enter from air to water it bent because it want follow a principle which is light take same time to travel in same distance in air and water therefore when it enter water it reduce speed so obiviously it take more time to travel a given distance then in air so to follow the principle that it take same time time to travel in air and water ,light bent inorder to decrease distance so by decreasing distance it will take same time

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 kind of meduim does not permit light rays to enter?
An opaque medium.
The bending of waves as they enter a different medium?
That's called "refraction".
Why do light waves slow down when they enter a new medium?
Light waves slow down when they enter a new medium because they interact with the atoms or molecules in the medium, causing them to be absorbed and re-emitted. This process delays the wave propagation, resulting in a decrease in speed.
What is effect on wavelength of light when it enter dense medium?
When light enters a denser medium than it was previously travelling in, the wavelength gets shorter because the speed of the light slows down: v=w/f where v is the velocity of a wave, w is the wave length, and f is the frequency. When light enters the new medium, f does not change but v decreases so w also decreases. Actually, the density of the medium is not accurate. The medium is not denser it just is "optically denser" which means it has a higher index of refraction. It has nothing to do with actual density, which is weight divided by volume.
