Cause light is a wave of moving particles (photons) that travel through different mediums but a medium is not needed to produce light, energy is. The speed, frequency and wave length all change with changing mediums. ie when u put a pool net in the water and look down the shaft it looks bent, this is the light entering a diff medium and changing speed and direction.
What else can I help you with?
Why is it important to explain the speed of light together with the medium in which the light travels?
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
Does light travels in waves and is required in a medium?
Yes, it travels in waves, but it doesn't need a medium.
What is the bending of light when it travels from one medium to another?
The bending of light when it travels from one medium to another is called refraction. This bending occurs due to a change in the speed of light as it moves from a medium with one optical density to a medium with a different optical density.
What type of medium does light travels fastest?
A vacuum.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Why Refractive index the medium is always greater than 1?
The refractive index indicates how much light is slowed down as it travels through a medium compared to its speed in a vacuum. Since light travels more slowly in a medium than in a vacuum, the refractive index of the medium is always greater than 1.
A disturbance that travels through a medium as a longitudinal wave?
Light does that.
In which medium Light travels faster in glass or water?
In water
When light travels from one medium to another which factors changes?
When light travels from one medium to another, factors that change include the speed of light, the wavelength of light, and the direction of light. These changes are caused by the different optical properties of each medium, such as refractive index and density.
Does Light Travel More slowly in a Medium?
Light travels at its maximum velocity c in a vacuum. In a medium with a certain refractive index, it is slowed down and travels with velocity c/index
Can light travel through a vacuum, and if so, how does it behave in the absence of a medium?
Yes, light can travel through a vacuum. In the absence of a medium, light behaves as an electromagnetic wave, moving at a constant speed of about 186,282 miles per second.
What is the material through which light travels like air or water?
"air", "water" "glass" - generically a medium.
