The speed at which light travels through a substance such as air depends on its density, which in turn depends in part on temperature.

Can the speed of light depend on air temps temperature?
Yes, but the difference is negligible.
Why does speed seem to depend on air temperature?
Its the fuckining helmet
Do the speed of light depend on air temperature?
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.
Why does the speed of sound depend on the air tenperature?
It is all about the nature. Temperature causes the sound speed.
Does the speed of light depend on wavelength?
No it doesn't. Do you have any more questions ?No, it does not.
Why does the speed of sound depend on air tempersture?
The speed of sound through a medium depends on the density of the medium and the density of air is affected by temperature.
Which factors affect the velocity of light?
The speed of light in a vacuum is constant. Otherwise, the speed of light will depend on what materials it travels through. For example, the speed of light in air is similar to the speed of light in a vacuum; in water, it is quite a bit slower.
What is the speed of sound in air when the air has a temperature of 20degree celies?
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.
Speed of radio signal in air?
-- 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.
How does the speed of light change when it enters the water?
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.
Compare the speed of light with the speed of sound at 0 degrees celsius?
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.
How much faster is the speed of light compared to earth speed?
The speed of light is not always fixed at 299792458 m/s. In earth's atmosphere, the speed of light slows, though this is negligible. In water, light travels at 75% of c, and in a diamond, light travels at .40 c. C is the speed of light, rounded to 300,000 km/s.
