With an exhaustive internet search lasting literally seconds, I found that the refractive index
of air at sea level is 1.000293 . That was just what I was looking for. It tells us that the speed
of light in sea-level air is (speed of light in vacuum) / (1.000293) .
(186,282.397) / (1.000293) = 186,227.8 miles per second .
What else can I help you with?
What is farster the speed of light or the speed of sound?
The speed of light is more than 850 thousand times the speed of sound.
Speed of light in gas and air at sea level?
The speed of light in gas (like air) is approximately 299,792 kilometers per second. In air at sea level, the speed remains the same as the speed of light in a vacuum because air does not significantly affect the speed of light due to its low density.
Does lightning go at the speed of light?
The speed of light is always constant. In air or vacuum, it is 299,792,458 m/s.
Speed of light through air in seconds?
Trough vacuum, it'd be 2.997.924.562 metres/second; Through air, it'd be 2.997.025.450 metres/second; both round to 3.000.000.000 metres/second, or 300.000 kilometres/second.
How do the speed of light and the speed of sound compare through air?
The speed of light is significantly faster than the speed of sound in air. The speed of light in a vacuum is approximately 299,792 kilometers per second while the speed of sound in air is about 343 meters per second. This means that light travels almost a million times faster than sound through air.
What is the speed of light in the air?
186,000 miles per second.
What is the difference in the speed of light between water and air?
The speed of light is slower in water than in air. In a vacuum, light travels at about 186,282 miles per second, but in water it slows down to about 140,000 miles per second.
What is farster the speed of light or the speed of sound?
The speed of light is more than 850 thousand times the speed of sound.
Speed of light in gas and air at sea level?
The speed of light in gas (like air) is approximately 299,792 kilometers per second. In air at sea level, the speed remains the same as the speed of light in a vacuum because air does not significantly affect the speed of light due to its low density.
What is the difference between the speed of light and the speed of sound?
The speed of light is much faster than the speed of sound. Light travels at approximately 186,282 miles per second in a vacuum, while sound travels at about 1,125 feet per second in air.
Speed of light and speed of sound?
Speed of light in vacuum is a constant which is denoted by c and is 1,86,000 miles/sec or 299,792,458 meters/second. In dry air at a temperature of 20 degrees Celsius speed of sound is 343 meters/second.
What is the speed of electromagnetic waves in air?
About the same as in a vacuum - 300 million meters/second.
Does sound and light travel at the same speed?
No, sound and light travel at different speeds. In a vacuum, light travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second), while the speed of sound in air is around 767 miles per hour (1,235 kilometers per hour).
How fast is the speed of sound and speed of light added together?
The speed of sound in air is about 343 m/s, and the speed of light in a vacuum is about 299,792 km/s. When added together, the speed of sound and the speed of light do not directly add up because sound requires a medium to travel through, while light can travel in a vacuum.
What travels faster in air sound or light and how do you know this?
Light travels faster in air than sound. This can be confirmed by observing the speed of light (about 186,282 miles per second) and the speed of sound (about 1,125 feet per second) in air. Additionally, light can travel through a vacuum, while sound requires a medium such as air to propagate.
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.
Does lightning go at the speed of light?
The speed of light is always constant. In air or vacuum, it is 299,792,458 m/s.
