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.
Whenever it goes from a medium with one refractive index to one with a different refractive index.
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
Of course not,it is not true. The speed of light decreases
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
The speed of the light decreases, and its wavelength increases by the same factor.
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.

When a wave period decreases, speed increases.
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
light undergoes refraction when the matter changes the speed of light
wavelength = speed of light/frequency so we rearrange frequency = speed of light/wavelength Hopefully you can figure it out from here...
The speed of the light decreases, and its wavelength increases by the same factor.
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
The speed of light depends on the electrical properties of whatever substance it's in. It has nothing to do with what substance it used to be in before, or what substance it's going into next. -- If it goes from air into vacuum, its speed increases. -- If it goes from air into water, its speed decreases. -- If it goes from water into air, its speed increases. -- If it goes from water into diamond or jello, its speed decreases.
c divided by the index of refraction of the medium = the speed of light in the medium.
