speed of light in the air
speed of sound in the air
Are they the same? Or are they not?
The speed of light and the speed of sound in the air are not the same.
The speed of light is constant in a vacuum, which is approximately 299,792,458 meters per second. However, when light travels through a medium like air, it slows down slightly. In air at standard temperature and pressure, the speed of light is approximately 299,702,547 meters per second, which is around 90 km/s slower than its speed in a vacuum.
On the other hand, the speed of sound in air is approximately 343 meters per second at standard temperature and pressure. This means that sound travels much slower than light in air. The exact speed of sound can vary depending on factors like temperature, humidity, and altitude.
In summary, the speed of light in air is significantly faster than the speed of sound in air.
