Light always travels at the speed of light.
The only time that's 299,792,458 meters per second is when the light is in vacuum.

When is the only time that light waves travel at thespeedof light?
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.
When is the only time that light waves travel at the speed of light (186272 miles per second)?
When it is moving through a vacuum.
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Differences between light and sound waves?
The differences between light and sound are as follows:Light can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Light waves are electromagnetic waves while sound waves are mechanical waves.Light waves are transverse while sound waves are longitudinal.Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of light in a medium is constant. The velocity of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a light wave, the electric and magnetic vectors oscillate.Light waves can be polarized, but sound waves cannot.Light waves travel much faster than sound waves. The speed of light is a physical constant. Its value is exactly 299,792,458 metres per second in vacuuum. The speed of sound is 343 metres per second in dry air at 20°C.And finally, a simple one - you can see light while you can hear sound.
What travels at light speed besides engines?
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
When is the only time sound waves travel the same speed as light?
They never do.
When is the only time that light waves travel at thespeedof light?
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.
When is the only time that light waves travel at the speed of light (186272 miles per second)?
When it is moving through a vacuum.
What speed do radio waves travel in air?
Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light (186,000 miles per second). The only difference between them is their frequencies (or wavelengths)
How do you travel in the speed of light?
You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
When is the only time light wavesd travels at the speed of light miels per second?
Light waves always travel at the speed of light ... whatever it may be inside the material they're traveling through. They only travel at 300,000 kilometers (186,282 miles) per second in vacuum.
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Does a radio wave travel faster than a sound wave?
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
What is the only time that light waves travel at the speed of light?
Light always travels at the speed of light. The only time that's 299,792,458 meters per second ( " c " ) is when it's traveling in vacuum.
Can humans travel with light waves?
Only with a really light surfboard.
All waves need a medium to travel?
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
How are electromagnetic (or light) waves different from water and sound waves?
Light waves and electromagnetic waves can travel through empty space. Water waves can only travel through matter. Hope this helped!
