The frequency of the light remains unchanged as it depends on the source of the light rather than the medium its traveling in.
Frequency / period, wavelength and amplitude may all vary depending on the material through which a wave is passing.
The frequency of the wave doesn't change.

refractionRefraction
Light refracts when is crosses the boundary between two materials. That means that is the light is coming in at one angle, then it will change direction at the interface and have a different angle moving out from the other side. There is an old formula called Snell's Law that predicts the exit angle in terms of the properties of the material, i.e. in terms of the index of refraction. There is reflection as well. Some light bounces off of a boundary and some is transmitted.
A refracted ray passes through the medium, at a different angle to the normal than the incident ray. by Ronan Lavery
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.
Refraction occurs when a wave bends as it crosses the boundary between different mediums (eg. air to glass). The wave bends because waves travel at different speeds in different mediums. When a wave enters a more dense medium (eg. air to glass), the wave slows down, and bends towards the 'normal'. When a wave enters a less dense medium (eg. glass to air), the wave speeds up, and bends away from the 'normal'. * The normal is an imaginary line which is perpendicular to where the light is entering the new medium.
it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.
A wave undergos refraction when it crosses the boundary between two media in which it has different speeds.

4 runs! It crosses the rope with a bounce or role's.
The first few showed the dominant characteristics, but after so many crosses, the recessive traits began to show.
