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 the 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 is when the light is in 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.
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.
Which layers can S-waves travel through?
s-waves travel through solids only
Which forms of matter can primary and secondary seismic waves travel through?
Primary seismic waves are longitudinal waves. Longitudinal waves can travel through solids, liquids and gasses (although seismic waves are of to low a frequency to normally be heard). Secondary seismic waves are transverse waves and only travel through solids.
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!
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!
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.
Is sound energy the only energy that uses waves to travel?
No, light travels in waves too.
Can wave travel a vacuum in sopce?
Yes, but only electromagnetic waves, such as visible light or radio waves. Mechanical waves like sound require a medium to travel.
When is the only time sound waves travel the same speed as light?
They never do.
What are the only type of waves that can travel through the emptiness of space?
Sound and Light
Do surface waves require a medium?
Yes. By definition, surface waves will travel at or near the surface of a medium. Only electromagnetic waves (light, radio, & etc) can travel through a vacuum.
What type of wave requires no medium to travel through?
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
When is the only time that the 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 is when the light is in vacuum.
