With increase in the temperature of the medium, the speed of light
With an increase in the temperature of the medium, the speed of light generally decreases. This is because higher temperatures increase the density of the medium’s molecules, which leads to more frequent interactions and absorptions of photons, temporarily slowing down the propagation of light.

With an increase in the temperature of the medium, the speed of light generally decreases. This phenomenon occurs because higher temperatures increase the density of the medium’s molecules. As light passes through the medium, it interacts with these molecules, which can temporarily absorb and re-emit photons. These interactions cause delays in the transmission of light, resulting in an overall decrease in its speed compared to when the medium is cooler and less dense. While the effect is usually small and varies depending on the specific properties of the medium, such as its refractive index and composition, the trend of decreasing speed with increasing temperature is consistent across different materials. Understanding how temperature affects the speed of light is essential in fields such as optics, atmospheric science, and material physics, where precise measurements and predictions of light propagation are critical for research and technological applications.
