Where is the speed of light greater than the speed of light in water?

The speed of light through vacuum is constant.
The speed of light through air is slightly less.
The speed of light through water or some other medium is even less than that.
The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).

Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
What happens to the speed of light when it travels from air into water?
the speed of light never changes but when the light beam goes from air to water, it refracts. this is when the light beam alters direction because it hits an object of greater or less density (in this case it is higher).
Is the speed of light in water should be more than the speed of light in a vacuum?
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
Why are electrons travel at greater than speed of light in television?
They don't. Nothing can exceed the speed of light. Electrons in a television travel much slower than the speed of light.
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Why the speed of electron beam is greater than the light speed in cathode ray oscilloscope?
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
Is the speed in water vapor greater than speed in water?
Not the speed of sound.
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Is the speed of sound in steel greater than speed in water?
Yes.

Light travels faster through water n 1 33 than it does through glass n equals 1 5?
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
Is the speed of light in water should be more than the speed of light in a vacuum?
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
Why are electrons travel at greater than speed of light in television?
They don't. Nothing can exceed the speed of light. Electrons in a television travel much slower than the speed of light.
Why speed of light is greater than speed of sound?
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.
Does water reflect or refract and why?
Both.Water is transparent to visible light but the speed of light in water is different to the speed of light in air. As a result, light rays travelling from air to water are usually refracted. However, as is the case at any interface between transparent media, light rays which hit the surface of the water at an angle greater than the critical angle are reflected.
