Why speed of light is greater than speed of sound?

The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.


Is the speed of sound 186000 miles per second?

No, the speed of light is 186,282.4 miles per second. The speed of sound at sea level is about 0.2114 miles per second.


What is the ratio of speed of light in a vacuum to the speed of sound in air?

In a rough, round figure? 930,000 to 1. Sound travels roughly 1/5 of a mile per second in air. Light travels 186,000 miles per second in a vacuum. In five seconds sound travels one mile. In five seconds, light travels 930,000 miles in a vacuum.


How does the speed of a wave affect its wavelength?

This can be answered using light or sound. Light will remain at a constant speed regardless of frequency or amplitude. Its shift in frequency (Doppler shift) is caused by the extreme distances the light had to travel to get here. Still it remains at the same speed. Sounds speed will change with local conditions. Also subject to an audible Doppler shift when a constant note is moved past you you can hear the pitch shift. The motion compresses the sound as it approaches and spreads it out as it moves away from you.


What is mach regarding speed?

That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
