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 ...

Sunlight takes approximately 8 minutes and 16.6 seconds to reach the Earth. This duration is based on the average distance between the Earth and the Sun, which is about 149.6 million kilometers (92.96 million miles), and the speed of light ...
The speed of light in air is approximately 299,792,458 meters per second (m/s). This speed is slightly slower than in a vacuum due to interactions between light and air molecules, which cause slight delays in its propagation compared to its ...
The maximum duration of a total solar eclipse, when the Moon completely covers the Sun’s disk, can last up to several minutes. The exact duration depends on the geometry of the Sun, Moon, and Earth during the eclipse event.
A solar eclipse occurs when the Moon passes between the Sun and Earth, blocking all or part of the Sun’s light from reaching Earth. This alignment causes the Moon’s shadow to fall on Earth’s surface, creating a temporary darkening of ...
