The speed at which light travels through a substance such as air depends on its density, which in turn depends in part on temperature.
Yes, but the difference is negligible.
No, the speed of light in a vacuum is constant and does not depend on wavelength. However, light can travel at different speeds in different mediums, such as air or water, due to interactions with the medium.
Its the fuckining helmet
The speed of light in vacuum is 299,792,458 meters per second,and somewhat less in any material medium, including air.The speed in air depends slightly on the density of the air, and sodepends on the temperature, pressure, and humidity of the air.This is the dependence that's responsible for the gently curvatureof light and radio over long distances through air.
It is all about the nature. Temperature causes the sound speed.
The speed of light in a vacuum is constant and does not depend on external factors like temperature. However, when light passes through a medium other than a vacuum, such as air or water, its speed can be affected by factors like the refractive index of the medium.
The speed of sound through a medium depends on the density of the medium and the density of air is affected by temperature.
That will not only depend on the temperature, but also on the exact composition of the air (such as, whether it is dry or humid), and possibly on the pressure. The typical speed of sound at 20 degrees C is approximately 343 meters/second.
-- The speed of radio in air is the same as the speed of light in air.-- That in turn depends on the temperature, pressure, and humidity of the air.-- At 'STP' (standard temperature and pressure) the refractive index of airis listed as 1.00027.So the speed of light/radio would be 99.972% of the speed in vacuum.That's 299,711,536 meters per second, down from 299,792,458 in space.
The speed of light has nothing to do with the temperature of the vacuum. It is c = 299 792 458 meters per second. The speed of sound has much to do with the temperature of the air. At 0 degrees Celsius the speed of sound in dry air is c = 331.29 meters per second.
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.
