Which is faster, sound or light ! why ?

Answer 1

ya it is light.
reason.sound requires a medium to travel where as light can travel without a medium.soun travels in waves so its atoms have to vibrate the other atom,which takes time.so we can conclude that light travels faster than sound

Answer 2

Light is faster.
Reason:- When you travel by a plane going faster than 763 Miles per hour, you will notice that you will not hear the sound of the plane, but you can still see the engines that are making this noise from the plane. The speed of sound can be easily reached, because today, even a car can go to 200 miles per hour, so a jet plane can go much more. however, we can still see the planes moving, so light is faster.

Answer 3

Sound is easiest. Sound is molecules banging into other molecules. A simple example is a slinky stretched across the front of the room. Push onone end back and forth into the slinky, not side-to-side or up-and-down.Each loop pushes on the next loop. The motion started at one end eventually reaches the other end. This is just how sound travels. Vibrations at aspeaker bang into molecules, perhaps air molecules. These bang into the
next molecules. This continues until air molecules bang into your eardrum. SOUND REQUIRES MEDIUM TO TRAVEL. (Velocity = frequency * Wavelength). In case of sound frequency is low.
Light vibrates side-to-side. You can show this with a slinky, too. Light, however, does not make the air vibrate. Light is little packets of electrical energy travelling through space. Faster electrical vibrations make shorter packets. The energy is then more tightly packed. Light requires no medium to travel. It has high frequency than sound.

Answer 4

Light is faster than sound.

Answer 5

well,sound waves travel faster
