Light ray and gamma ray both travel in a straight line.


Laser rays are many light rays focused into a single light ray. That ray is a laser ray. The more lights rays focused into a single ray, the more powerful the laser ray.


Gamma rays travel exactly the speed of light because gamma rays are light


Gamma rays. Since they are electromagnetic waves, they travel at the speed of light.



There is no standard collective noun for a group of light rays.However the noun 'ray' is a collective noun as: a ray of light.The collective nouns for a group of 'rays' are:a fever of stingraysa fever of manta rays


Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.



Light is a term we give to electromagnetic radiation in the visible spectrum. All electromagnetic rays travel at the speed of light.


If light rays did not travel through space there would be no way for them to reach Earth.


Electromagnetic waves, like light, radio, ultraviolet, infrared, x-ray and gamma rays all travel at the speed of light.


Yes. Gamma Rays are photons (like visible light, just at another part of the electromagnetic spectrum). They travel with constant velocity at the speed of light (only in a vacuum). Although the original speed of the gamma ray varies.


What seeing is, is seeing rays of light - you see light.


You can. without rays of light you could not see


This is the definition of the reflection of a light ray. The other term related to light rays is refraction, which is the bending of a light ray as it passes from one substance into another.


X-rays are a type of light ray, but not all light rays are X-rays. X-rays have a wavelength ranging from 10 to 1/100 of a nanometer. Because humans can only see light with a wavelength between 700 and 400 nanometers, it is invisible to us. X-ray radiation is harmful to humans, as well.


A ray of light can travel in any direction, so an infinite number.


nothing they travel in straight line


X-rays are different from all of these but are similar to gamma rays. Both X-rays and gamma rays are forms of electromagnetic energy. X-rays have slightly longer wave lengths than gamma rays and have lower penetration power as compared to gamma rays. More over, X-rays are "waves" and part of the electromagnetic spectrum, and hence travel with the speed of light in vacuum i.e c, whereas alpha and beta rays are not waves but are energy particles that are radiated by unstable atoms and do not travel at the speed of light (except beta part. which almost does). Gamma rays apart from having a low penetration power compared to x-rays are also radiations from the nucleus whereas x-rays are emitted by electrons in excitation in order for the atom to reach a more stable state.


Yes, they travel some fast!


Rays are used to model the propagation of light through an optical system



No, x-rays travel at the same observable speed as any other electromagnetic wave including light.
