No, light does not always travel at the same speed in all mediums. Its speed can vary depending on the medium it is passing through.
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
All photons travel at the same speed in a vacuum, which is the speed of light, but their velocities can vary when passing through different mediums.
All colors of light travel at the same speed in a vacuum, which is the speed of light. However, in mediums like air or water, the speed of light differs for different colors due to their different wavelengths and refractive indexes. Blue light generally travels slower than red light in these mediums.
Light waves travel faster in a vacuum than in other mediums because there are no particles in a vacuum to slow down or scatter the waves. This allows light to move at its maximum speed, which is about 186,282 miles per second.
Light rays always travel in straight lines in a medium with a uniform refractive index. This is known as the principle of rectilinear propagation of light. However, in mediums with varying refractive indices or when interacting with surfaces, light rays can bend, reflect, or refract.

Yes, the speed of light is constant in a vacuum, but it can change when passing through different mediums, such as air, water, or glass.
Light typically travels through different mediums by either being absorbed, transmitted, reflected, or refracted. The speed and direction of light can change depending on the properties of the medium it is passing through, such as its density and composition.
Light does not accelerate. In a vacuum, light always travels at a constant speed of approximately 299,792 kilometers per second, known as the speed of light. It only changes speed when it passes through different mediums.
Electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second in a vacuum. This speed can vary in different mediums, such as air or glass, where light may travel slower than its maximum speed in a vacuum.
The speed of light in a vacuum is constant, it's value is c. However c changes with different mediums (air, water...etc). It depends on the index of refraction, n. For example, here is how you would calculate the speed of light in air: vair= c/nair In other words, the speed of light changes depending on the medium that it travels through.
Light can slow down in different mediums because it interacts with the atoms and molecules in those materials. When light enters a medium, it can be absorbed and re-emitted by the particles in the material, causing it to travel at a slower speed than in a vacuum. This process is known as light scattering and is responsible for the phenomenon of light slowing down in different mediums.
But they do !
