What is the speed of light vs sound?
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.
What is a speed of light?
speed of light, speed at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second.
How much faster is light than sound?
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 3×1010 m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile.
What is the conversion factor for mph to km h?
1.6093440006147
The conversion factor is 1.6093440006147; so 1 mile per hour = 1.6093440006147 kilometers per hour. In other words, the value in mph multiply by 1.6093440006147 to get a value in km/h.
How to convert speed of sound to miles per hour?
To convert a speed of sound measurement to a mile per hour measurement, multiply the speed by the conversion ratio. Since one speed of sound is equal to 767.269148 miles per hour, you can use this simple formula to convert: The speed in miles per hour is equal to the speed of sound multiplied by 767.269148.
