What is the typical velocity of gamma rays?
The value obtained is (2.983+/-0.015)×1010 centimeters per second.
The numerical value of the speed of electromagnetic radiation in a vacuum is?
299,792,458 meters (186,282 miles) per second ... the speed of all forms of electromagnetic radiation, including light, in vacuum. The speed is slightly less in air, water, glass, jello, etc.
What is the value of index or refraction of a medium?
The index of refraction tells you by which factor the speed of light in the medium is slower than in a vacuum. This value is 1 for a vacuum, and a number greater than 1 for other media. The exact value depends on the medium.
How fast does a gamma ray burst travel?
The speed of electromagnetic radiation is a constant. Its value is exactly 299,792,458 metres per second (about 186,282 miles per second) in vacuum, somewhat slower in material media. To give you some kind of a feeling for that speed, it would be the equivalent of 7 1/2 times around the Earth in one second. The speed is the same for all electromagnetic radiation. Gamma rays are one form of it. Others include radio, microwave, visible light, ultraviolet, X-rays, etc.
What is velocity of light in vacuum?
The speed of light depends on the refractive index of the medium through which it is travelling. It reaches its maximum value in vacuum. This is approx 299,792,458 metres per second.
What is the typical velocity of gamma rays?
The value obtained is (2.983+/-0.015)×1010 centimeters per second.
What the value of the index of refraction of a medium?
It's the speed of light in vacuum divided by the speed of light in that medium.
What is the value of c in a vacuum Give the numerical value as well as the definition?
C represents the speed of light. In a vacuum it is 299,792,458 meters per second. C is also the maximum speed at which anything in the universe can travel.
What is the value of c in a vacuum?
Speed of light is constant which is 3*10^8m/s.

What is the exact value of the speed of light in a vacuum?
The speed of light in a vacuum is 299 792 458 meters per second or 983,571,056.43045 feet per second or 186,282.397 miles per second or 670,616,629.2 miles per hour.
Is it true that the speed of light in vacuum is the same value regardless of wavelength?
Yes. No experimental evidence has ever been found that would suggest that any wavelength of light travels at a different speed than any other. We speak, of course, only about electromagnetic radiation in a vacuum.
What is velocity of light in vacuum?
The speed of light depends on the refractive index of the medium through which it is travelling. It reaches its maximum value in vacuum. This is approx 299,792,458 metres per second.
Moving along the electromagnetic spectrum from radio waves to gamma rays frequency increases so wavelength?
The wavelength decreases.The speed of light is the speed of all electromagnetic radiation (such as radio waves, light waves, gamma rays, etc.) in vacuum.The speed of light (c) is a physical constant with the exact value of 299,792,458 m/s.speed of light = frequency x wavelengthso when frequency increases, wavelength decreases .
What transperent objects can slow the speed of light?
Anything that is transparent i.e. allows light to pass through, can slow the speed of light. The speed of light C is measured in a vacuum at 2.98 x 108 ms-1, if light is able to pass through any object that is not a vacuum e.g. water, this value will be less as the medium is more dense than a vacuum. Light is made up of particles called Photons, which will collide with the particles that make up any medium, slowing them down. Therefore, the only medium in which light can travel at it's maximum speed is in a vacuum, as by definition a vacuum is empty space and there will be no collisions.
