No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
Use the relation:speed in a medium = speed of light in a vacuum / refractive indexi.e. v=c/nHencev = 300000000/1.333 = 225060000 m/s

No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
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.
No, it shouldn't. And it isn't.

Speed of light in water = speed of light in vacuum/refractive index of water

The speed of light is a maximum in a vacuum. In other media, such as air or water, the speed of light is slower due to interactions with the medium's particles.

glass
The speed of light in water is slower than in a vacuum. This is due to the higher refractive index of water compared to air, causing light to bend more in water. In a glass, the speed of light is also slower compared to a vacuum, though the exact speed will depend on the composition of the glass.
The speed of light in a vacuum is constant. Otherwise, the speed of light will depend on what materials it travels through. For example, the speed of light in air is similar to the speed of light in a vacuum; in water, it is quite a bit slower.
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
