Light changes speed when it passes through a transparent substance, based on the refractive index. For diamond, the dense crystal slows light to less than half of its velocity as measured in a vacuum.

∙ 13y agoThe speed of light depends on the index of refraction of the material it travels in. The refractive index is defined as n=c/u where c is the speed of light in vacuum and u is the speed of light in a material.
The speed of light in vacuum however is constant and cannot be changed.

∙ 11y agoThe speed of light depends on the electrical properties of the medium (stuff) it's traveling
through. Its speed is maximum in vacuum ... 299,792,458 meters per second ... and it has
different speeds in any material ... e.g., air, water, glass, jello, etc. As long as the light stays
in the same material, its speed doesn't change.

What type of speed is light?
Light is a type of wave; it is not a type of speed.
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
How elasticity of a medium affects the speed at which sound travels?
by causeing larger sound waves through objects
Does speed of light depend on wave or particle nature?
No.
Which waves travel the fastest?
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
Does color of a laser affects the velocity of the light wave projected by a laser?
No. Light travels at the same speed no matter what.
What wave property affects the speed of a wave?
Both the wavelength and the frequency of a wave affect the speed of a wave.
What type of speed is light?
Light is a type of wave; it is not a type of speed.
How does the speed of a photon compare with the speed of an electromagnetic wave?
Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
Why does light have a speed?
Light is an electromagnetic wave and, like all waves, it has a speed.
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
How elasticity of a medium affects the speed at which sound travels?
by causeing larger sound waves through objects
Do the color of a laser affects the velocity of light wave by the laser?
No. The color is determined by the light's *frequency*, but, as Einstein proved, there is one and only one velocity at which light can propagate, c or the speed of light. All light propagates at this same velocity (there are ways to slow it down slightly, e.g. by passing through dense material, but this affects all light the same). The speed of light being a constant is one of the very foundations of modern physics.
What is the the speed at which a wave travel through a medium?
the true answer is light speed
Why does an electromagnetic wave in space never slow down?
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.
How do you calculate the frequency of light given its wavelength?
The speed of light = the frequency X wave length.. therefore:- Frequency = The speed of light (m/s) _______________ wave Length (m) Where the speed of light : 2.9979 x 10^8 (m/s)
How does the speed of a light or sound wave be changed?
,,,l;.
