It slows from c to c/n where n is the refractive index of water
Light can be absorbed, reflected, refracted, or transmitted when passing through different mediums. The speed of light may change depending on the medium it is passing through, which can result in bending or changing direction. The refractive index of a material determines how much the light will be bent as it passes through.
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
When light energy is not absorbed, it can be reflected, refracted, or transmitted. Reflection occurs when light bounces off a surface, while refraction happens when light passes through a medium and changes speed. Transmission involves light passing through a material without being absorbed.
When light passes through different mediums, such as air, water, or glass, the distance between waves (wavelength) can change. This is because the speed of light varies in different mediums, causing the wavelength to either increase or decrease.
When light passes through a prism, it is refracted, which means it bends due to the change in speed as it moves from one medium to another. This bending occurs at different angles depending on the wavelengths of light, resulting in the separation of white light into its various colors. This separation of light into its component colors is known as dispersion.
it travels at c (speed of light in a vacuum)
It moves at a slower speed!
The speed decreases.
It increases.
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.

When the speed of light in the two media is not the same.
Diffraction.
When light energy is not absorbed, it can be reflected, refracted, or transmitted. Reflection occurs when light bounces off a surface, while refraction happens when light passes through a medium and changes speed. Transmission involves light passing through a material without being absorbed.
Zero (0) light cannot pass through opaque materials.
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
