Why does light chage in derection when it crosses the boundary between transparent object?
This is due to difference in mediums.When light enter from lighter mediam that is air to some denser transparent medium like glass it bends toward normal and vice versa.
What happens to a ray of light that slows down when it hits a new medium at an angle?
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.
What is the light ray when it enter or exits a water air at an angle of 15 degrees with the normal?
sometimes bends towards the normal
What happens to waves when they enter a denser medium at a angle?
They are refracted, and the new angle of travel appears as an increase to the initial angle of incidence.
When light rays enter a medium at an angle they?
The light rays will refract towards the normal of the medium and emerge out at the same angle.

How or why does light enter water by a limited distance?
Light enter the water base on the principle of refraction of wave,during this process light moves from a denser medium to a less denser medium leading to the change in wavelength of the light That, however true, is not an answer to the question. (VanZanten)
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 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.
What is the bending of a wave as it enters a new medium at an angle?
When a ray of light travels from one transparent medium into another medium, it bends while crossing the interface, separating the two media. This phenomenon is called refraction.
Why phase change of 180 takes place when wave enter from rarer medium to denser medium?
The displacement is a peculiar state, due to the fact that this is one of the special situations in which energy is completely destroyed and conservation of energy does not take place; hence the phase change
Why does wavelength o light decrease when enter to denser medium?
That is because the light's SPEED decreases. Also, because the frequency doesn't change. As a reminder, the wavelength is equal to the speed of the wave, divided by the frequency.
