The speed of light and its wavelength decreases when it enters a new medium. The physicist Snell showed that it can vary.
Refracts
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
The amount of initial energy affects the wavelength of a mechanical wave moving through a medium. A mechanical wave requires an initial energy input to be created. Once this initial energy is added, the wave will travel through the medium until all the energy has been transferred.
Frequency never changes since it depends only on source. Speed can either increase or decrease, depending on the direction of travel of light. This would cause an increase or decrease in wavelength respectively. Speed increases when light travels from an optically denser medium to an optically less dense one. (For example, when light travels from water to air) Speed decreases when light travels from an optically less dense medium to an optically denser medium.
direction changes.
Wave refraction to change in the wave speed or wavelength when a wave travels from one medium to another.
A medium.
The speed of light is not affected by the density of the medium. Its the path of the light that is affected . Phenomenon like reflection or refraction take place when the light goes to different medium
Refracts
Refraction comes into play only when the light travels from one medium into another medium. The speed of light is different in different media, so the wavelength changes due to refraction. The formula for wavelength is the ratio of the speed of light to its frequency. The most important point is that the frequency character of light remains constant eventhough it travels in different media. Hence the wavelength is directly proportional to the speed of light. So as speed changes, the wavelength also changes accordingly.

The Speed At Which Wave Travels Is Known As Wave Velocity.It Is Denoted As 'v' which Equals The Product Of Its Frequency And Wavelength.
The waves become smaller.
