Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.

When the speed of light changes the frequencywavelegnth changes?
The constancy of the speed of light in vacuum is the keystone of relativity. Because of this, the frequency/wavelenth of the light changes relative to the observer when the source is approaching or receding from the observer. That's why there is red shift. Usually, this is explained by analogy to the Doppler effect with sound waves, where the speed of sound is constant and the frequency has to changes as the relative motion changes.
What do you call it when light the speed of light changes as it passes through different meduims?
Diffraction.
How you calculate the speed of light in water?
Assuming the speed of light in air is already known (it is close to the speed of light in a vacuum), you might check how the light refracts when it changes from air to water (at what angle), and then use Snell's Law.
Why call light as E M wave which is not having neither electric nor magnet?
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

Why wavelenth doesnt change with speed of light?
It's actually the speed of light that doesn't change. The equation for wavelength is: WL= f/c or, wavelength (m) = frequency (cycles per second or Hz) / the speed of light (3x10^8 m/s). ***Notice that this equation implies that wavelength and frequency are inversely related. This means that as wavelength increases frequency decreases and vice versa.*** Light is the only constant in the equation meaning wavelength changes as frequency changes, but the speed of light doesn't change. Electromagnetic waves all travel at the speed of light. The only difference between an infrared wave (10^12 Hz) and a gamma wave (10^18 Hz) is a matter of frequency. In the case of visible light, the frequency is measured a bit more specifically using nanometers, a billionth of a meter. These range from about 400-750 nanometers. Find an electromagnetic spectrum that shows wavelength, frequency and a zoomed in picture of visible light. Pay attention to the relationships and patterns. It'll make this a lot easier to understand.

What is the equation for calculating wave speed?
wave speed= frequency/wavelenth
How do you calculate speed when the frequency and wavelength are given?
speed=frequency x wavelenth xD
How does the wavelenth changes when light travel from ane optical medium to another optical medium?
The wavelength of light changes when it travels from one optical medium to another due to a phenomenon called refraction. The speed of light is different in different media, causing the wavelength to either increase or decrease as it moves through the new medium. This change in wavelength is responsible for effects like the bending of light rays.
What is the exact wavelenth of green light?
The exact wavelength of green light is around 510 nanometers.
How is refraction linked to light speed?
When light enters a different medium (refracts), its speed changes.
What is constant and never changes?
The speed of light in a vacuum never changes.
When light enters a different mediumit's speed changes as it undergoes what?
When light enters a different medium, its speed changes as it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in speed.
When does light undergo refraction?
light undergoes refraction when the matter changes the speed of light
Which property of light will change when the medium of propagation changes?
The speed of light in a medium changes when the medium of propagation changes. The wavelength and direction of light may also change depending on the medium, due to factors like refraction.
What do you call it when light the speed of light changes as it passes through different meduims?
Diffraction.
What causes light to change directions?
The change in speed of light changes the direction.
