As a domain expert in the field of optics, I can provide a comprehensive explanation on the behavior of light as it interacts with different media, particularly water.
Light, as we know, is a form of electromagnetic radiation. It propagates in the form of waves, and its ability to travel through various materials is governed by the principles of physics. When light encounters a medium other than a vacuum, such as water, its speed and behavior are affected by the properties of that medium.
The speed of light in a vacuum is approximately \(3 \times 10^8\) meters per second. However, when light enters a medium like water, it slows down. This is due to the interaction of light with the particles of the medium, which causes the light to refract, or change direction, and also to slow down. The speed of light in water is roughly three-quarters of its speed in a vacuum, which is about \(2.25 \times 10^8\) meters per second.
The phenomenon of refraction is described by Snell's Law, which relates the angles of incidence and refraction to the indices of refraction of the two media. The index of refraction is a measure of how much a material can bend light. Water has a higher index of refraction than air, which is why light slows down and bends as it enters water.
Moreover, light can also be absorbed by water to some extent, depending on the wavelength of the light. Different wavelengths of light are absorbed at different rates, which is why water appears blue. This is because water absorbs longer wavelengths of light (such as red, orange, and yellow) more strongly than shorter wavelengths (such as blue and violet). The shorter wavelengths are scattered in all directions, giving the water its characteristic color.
Additionally, the clarity and purity of the water can affect how much light is transmitted, absorbed, or scattered. Pure water is quite transparent, but impurities, suspended particles, or dissolved substances can scatter light, reducing visibility underwater.
In summary, light does indeed travel through water, but at a reduced speed and with behaviors influenced by refraction, absorption, and scattering. These properties make water an interesting medium to study the fundamental principles of optics.

Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through. ... If I get a glass of a water then the light will go slower because light travel faster in air..Nov 19, 2013
