Why do wavelength of light changes when it travels from one medium to another?

It gets shorter due to slower speed. Beware: color depends on frequency, which doesn't change.
The frequency of light is defined by its wavelength. When light travels from air into water, there is a phase shift in the electromagnetic ripple, not a frequency shift.

∙ 14y agoThe wavelength of light is shorter in water than in air. Consider this: Wavelength = (speed) / (frequency)Looking at this fraction, you can see that as long as frequency remains constant, wavelength changes in the same directionas speed of light in the medium. More speed = more wavelength etc. Another way to remember it: The frequency is the number of waves that pass you in a second. If the waves are all moving slower but the same number of them pass you in a second, then each one has to be shorter. Right ?

∙ 11y agoBecause the speed of light changes. Wavelength is given by c / nu
nu is the frequency which character never changes though it changes from one medium to the other. c is the velocity of the wave ie speed which changes as it changes from one medium to the other.

What happens when light and its wavelength travels from one medium to another?
The speed of light and its wavelength decreases when it enters a new medium. The physicist Snell showed that it can vary.
When light travels from one medium to another which factors changes?
direction changes.
What does light do when it travels from one material to another?
Refraction is what light does when it travels from one material to another. Refraction is when the light changes direction because it is passing through one medium to another.
When waves travel from one point to another what is transferred through the medium?
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.
When a wave travels to one medium to another it?
Refracts

When is the speed of light increases or decreases after refraction?
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.
What is rave faction Exaples?
Wave refraction to change in the wave speed or wavelength when a wave travels from one medium to another.

What is another word for the substance in which a wave travels?
A medium.
Does amplitude of a wave changes when travels in a different medium?
Yes.
When a wave travels to one medium to another it?
Refracts
What happens when a wave changes medium?
On passing from one medium to another, the frequency of any wave stays constant. The wavelength changes such that the new wavelength equals the old wavelength multiplied by the old refractive index divided by the new refractive index. Lnew = Lold x (Nold/Nnew) Where L is the wavelength and N is the refractive index. The refractive index is a property related to wave velocity, which will vary in different mediums.
What is it called when ligh travels from one medium to another?
Refraction.
The speed at which a wave travels through a medium is called?
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.
