do velocity of light changes in hot or cold medium(air or water)...if it changes,wat is the reason for that change...wat effect the temperature of medium has on velocity of light?
pam said:but I expect that the effect is too small to have been measured.
ZapperZ said:The temperature effect is extremely important certain measurements, such as the recently published result from the Auger Observatory collaboration. It makes a lot of difference what the air temperature is when you're trying to collect the cerenkov light that these high energy particles are making as they go through the air. That's why they sample the air temperature often not just throughout the year, but in a day as well.
Zz.
The velocity of light in a medium is directly proportional to the temperature of the medium. This means that as the temperature of the medium increases, the velocity of light also increases.
The temperature of a medium affects the speed of light because it changes the density of the medium. As the temperature increases, the density decreases, allowing light to travel through the medium faster.
No, the velocity of light is not constant in all mediums. It varies depending on the properties of the medium, such as its density, composition, and temperature.
Yes, extreme temperatures can affect the speed of light in a medium. For example, at very low temperatures, the density of a medium may increase, causing the speed of light to decrease.
The speed of light in a vacuum is the fastest possible speed and is constant at approximately 299,792,458 meters per second. The speed of light in a medium is always slower than the speed of light in a vacuum and can vary depending on the properties of the medium.
