What is faster speed of light or speed of sound?

Best Answers

Speed of light is very much faster than the speed of sound. The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is 299,792,458 m/s, or 300,000 km/sec (186,000 mi/s). Where as the speed of sound is only 343 m/sec in dry air at 20C. read more

Even though sound isn't as fast as light the speed sound travels at isn't exactly slow. Something that travels at 761 miles per hour is still pretty fast. Objects such as planes that go faster than the speed of sound (761 mph) travel at Mach 1. Objects that travel 2 times the speed of sound (1522 mph) travel at mach 2. read more
