To put that in perspective, if you could travel at the speed of light, you would be able to circumnavigate the globe approximately seven and a half times in one second. Light travels at a constant speed of 1,079,252,848.8 (1.07 billion) km per hour. But just how fast does it travel? Speed of Light ( c): Its speed is considered a constant and an unbreakable barrier, and is used as a means of measuring distance.

Put simply, light moves at incredible speeds and is the fastest moving thing in the Universe. In so doing, they have gained a better understanding of light’s mechanics and the important role it plays in physics, astronomy and cosmology. Since the late-17th century, scientists have been doing just that, and with increasing accuracy. what is it made of – particle or wave, etc.) they have also sought to make finite measurements of how fast it travels. In addition to trying to discern its basic properties (i.e.

Since ancient times, philosophers and scholars have sought to understand light.
