How fast is the speed of sound in a vacuum?
Sound waves cannot travel in a vacuum.
How do sound waves travel compared to light waves?
light waves fast
How fast can light waves travel in a second if it's moving through a vacuum?
Approximately 186000 miles/second or 300000 kilometers/second

light waves fast
The speed of light indicates how fast light can travel in a vacuum?
Yes ... in a vacuum.
How fast can light waves travel in a second if it's moving through a vacuum?
Approximately 186000 miles/second or 300000 kilometers/second
How fast do sound waves travel through a vacuum?
You'd have to say that the speed of sound waves in vacuum is zero, becausesound can't travel through vacuum at all. Not even an inch. Sound needs amaterial substance to travel through.
Why is diffraction of sound waves more easily observed than diffraction of light waves?
sound waves travel fast than light waves
How fast can a radio wave travel to space and back to earth?
Radio waves travel at the speed of light which, in a vacuum, is about 3 x 108 meters per second.
How fast do electromagnetic waves travel through a vacuum?
300,000 kilometers/second, or 300,000,000 meters/second.
How fast can light waves travel?
The sped of light is 186,000 miles per second or 300,000 kilometers per second in a vacuum. In a diamond, one of the densest trasperant objects we know light travels alot slower.
What are similarities of light and sound?
They both travel in the form of waves, and they both travel very fast.
