Yes that's true. Roughly 880,000 times as fast, in fact.
Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves
Radio wave travel faster than sound wave. Radio wave is the same as light wave except at different wavelength. It travel at speed of light (3 x 108 m/s). Sound wave travel at only 330 m/s and probably can go up to 3,300 m/s in solid medium which is far slower than the speed of light.
Sound travels at the speed of sound, whereas radio waves travel at the speed of light. The speed of radio waves is much faster than the speed of sound. If you're seated high in the stands at a baseball game, watching it on the field and listening to the game on the radio at the same time, it's quite common to hear the crack of the bat on the radio before you hear it straight from Home Plate.
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
In air, light waves travel about 871 thousand times faster than sound waves.
About a million times faster
Ultrasonic means 'faster than sound'. This means no sound wave can be faster than sound.
Yes, both light and sound can be described as waves. Light waves are electromagnetic waves, while sound waves are mechanical waves. They both propagate through a medium, although light can also travel through a vacuum.
No light travels way faster
steel sound waves always go faster in solids
sound waves are faster in water than in land, light waves are faster in land
Supersonic waves are waves that can travel faster than normal sound waves.
