No.
We call it the "speed of light", but it's also the speed of radio, X-rays, heat,
ultraviolet, microwave, gamma rays, etc, and all forms of electromagnetic radiation travel at the same speed, as long as they're in the same medium (vacuum or material substance).
Light and radio waves are both forms of electromagnetic radiation and they follow the same basic laws of physics.
As far as we know, gravity.
The same. Both are electromagnetic waves; in a vacuum, they both travel at the speed of light.
All travel at the same speed through a vacuum
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.
In a vacuum radio waves travel at the speed of light, about 186,000 miles per second.
Both are forms of electromagnetic energy and travel at the same speed, which is the speed of light.
Yes.
It travels fastest in a vacuum.
No, slower.
No. Their speeds are identical.
no
Light travels fastest through vacuum.
Light spectrum is part of the electromagnetic radiation spectrum. Electromagnetic waves travel better and faster (light speed in vacuum) in vacuum.
No.
No.
Sound does not travel in a vacuum. It needs a medium in which to travel (unlike light) and so sound cannot travel in a vacuum. However, in a solid sound travels faster than in air.
No. All forms of electromagnetic radiation travel at the speed of light.
No. Both travel at exactly the same speed. The speed of light.
