As a domain expert in the field of physics, I can confirm that light is indeed faster than sound. Light, which is a form of electromagnetic radiation, travels at a constant speed in a vacuum, which is approximately 300 million meters per second (or about 186,282 miles per second). This speed is often denoted by the letter 'c' and is considered a fundamental constant in physics. On the other hand, sound is a mechanical wave that requires a medium (like air, water, or steel) to propagate. The speed of sound varies depending on the medium it's traveling through. In air at sea level and at a temperature of about 20 degrees Celsius, the speed of sound is about 340 meters per second. As mentioned in the reference, sound does travel faster in water and even faster in steel, but it still does not approach the speed of light. Therefore, the answer to the question "Is light faster than sound?" is a definitive yes. read more >>

Light doesn't need a medium to travel. 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.read more >>
