Why the speed of light decreases when it is in the medium?
Thank you.
Thank you.
The speed of light in a medium refers to the speed at which light travels through a specific material or substance. It is different from the speed of light in a vacuum, which is approximately 299,792,458 meters per second.
The speed of light in a vacuum is the maximum speed at which light can travel, while the speed of light in a medium is slower due to the interaction of light with the particles in the medium.
The speed of light in a medium is affected by the density, temperature, and composition of the medium. Light also travels at different speeds through different materials, such as air, water, or glass.
The speed of light in a medium can be measured using various methods, such as measuring the time it takes for light to travel through the medium or using refractive index calculations.
The speed of light in a medium is important in scientific research because it affects how light behaves and interacts with different materials. It is also a fundamental concept in fields such as optics, astronomy, and quantum mechanics.
