Refraction
The light rays will refract towards the normal of the medium and emerge out at the same angle.
when light rays enter a new medium in a new angle it may speed up or speed down
Refraction is the bending of light waves as they pass from one medium to another.

An opaque medium.
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)
Refraction is the bending of light waves as they pass from one medium to another.
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
Refraction
Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.
Three situations may arise when a light wave travelling from an optical medium to another optical medium strikes the second medium. They are as follows: 1. The light ray may bounce off of the medium to which it was travelling with a change in angle.This phenomenon is also known as reflection of light. 2. The light ray may pass through the second medium with a deviation in its angle of incidence. This is also known as refraction of light. 3. The ray may be absorbed by the second medium. If a light wave does not bounce off of an object then either 1. or 2. may happen. That light ray enter the second medium, or it may be absorbed by that medium.
