Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which one travels faster:sound or light waves?
A
Sound
B
Light
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

Detailed explanation-2: -The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales.

Detailed explanation-3: -So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186, 282 miles per second.

Detailed explanation-4: -The standard metric for the speed of light is that of light traveling in vacuum. This constant, known as c, is roughly 186, 000 miles per second, or roughly one million times the speed of sound in air.

Detailed explanation-5: -The speed of light is much faster than the speed of sound in air. If you want to compare, the speed of sound in air is   343 m/s and the speed of light is 3x1010 m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile.
