What is the speed of sound and light in KM?
Sound . . . 0.34 km/second Light . . . . 300,000 km/second
What is the speed of light converted to kilometers?
Speed of light c = 299792458 m/s × 1 km/1000 m = 299792.458 km/s. Speed of light c = 299792.458 km/s × 3600 s/ 1 hr = 1079252848.8 km/hr.
What is the speed of sound and the speed of light difference in km per s?
The speed of light in vacuum is 299,792,458 m/s usually rounded to 300,000 km/sec.The speed of sound at sea level is 343 m/s.The difference is 299,792,115 m/s.That's 99.999 886 % of the speed of light, and may also be rounded to 300,000 km/sec.
How long does light take to travel from the Earth to the Moon if the distance between them is 384000 km?
The speed of light is 300,000 km/second. If you divide the distance by this speed of light, you get the time in seconds: 1.28.
Speed of light kilometers per hour?
