The velocity of light in air is about 299,792 kilometers per second, while in water it is about 225,000 kilometers per second. This difference is due to the differing refractive indexes of air and water, which affects the speed at which light travels through these mediums.
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
The velocity of light is higher in air than in water. In a vacuum, light travels at its maximum speed of approximately 299,792 kilometers per second, which decreases when it passes through a medium like air or water due to interactions with the medium's atoms and molecules.
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.
Yes, the velocity of sound is greater in water than in air because water is denser than air, allowing sound waves to travel more quickly through it.
The velocity of light decreases when it enters glass due to its higher optical density compared to air. This causes the light ray to bend towards the normal line at the boundary between air and glass.
The velocity of light is highest in a vaccum; slightly slower in air, and a LOT slower in water.
The speed of the light decreases, and its wavelength increases by the same factor.

The velocity of light is greatest in fused quartz. The speed of light varies depending on the medium it travels through, with the highest speed occurring in materials that have low refractive indexes, such as fused quartz.
More resistance, caused by a greater density.
