The refractive index of diamond is about 2.42 . So the speed of light in it is
(speed of light in vacuum) divided by (2.42)
That's 123.9 thousand kilometers per second (about 77,000 miles per second).

How fast does light travel through copper?
Copper is opaque to light - light can not travel though it.
How fast does light travel through wind?
ans2. Light is an electromagnetic phenomena, and is unaffected by the motion of air.
How does light travel trough space?
Light goes incredibly fast through space, bouncing off objects.
How fast do gravitational waves travel through space?
Gravitational waves travel through space at the speed of light, which is about 186,282 miles per second.
Some fast do light rays travel?
Yes, they travel some fast!
What is meant by the refractive index of a diamond is 2.42?
The number is comparative. Refractive index is a dimensionless number that represents how fast radiation -- in this case, light -- travels through a medium, in this case, diamond. The number assigned to a diamond is the highest number on the scale. The scale includes gases, liquids and solids. This means that with a refractive index of 2.42, 'light travels 2.42 times as fast in vacuum as it does in a diamond'. You can read more about refractive indices, below.
How fast does light travel through space in miles per hour?
670 616 629 mph
How do sound waves travel compared to light waves?
Sound waves require a medium to travel through, such as air, water, or solids, and they propagate by causing particles in the medium to vibrate. Light waves, on the other hand, can travel through a vacuum and do not require a medium. They propagate as electromagnetic waves and can travel through empty space.
How fast can light waves travel?
The sped of light is 186,000 miles per second or 300,000 kilometers per second in a vacuum. In a diamond, one of the densest trasperant objects we know light travels alot slower.
How fast does light travel per foot?
the speed of light
How fast does light really travel?
it can travel from 380nm [nanometres] to 740nm
What is darkness and how fast does it travel?
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
