The speed of light is important because it’s about way more than, well, the speed of light. In the early 1900’s Einstein realized just how special this speed is. The old physics, dominated by the work of Isaac Newton, said that the universe had a fixed reference frame from which we...
One of the first measurements of the speed of light was by Ole Rømer in 1676 by observing themoons of Jupiter. The speed of light was first measured to high precision in 1879 by the Michelson-Morley Experiment. How do we know the speed of light? Ole Rømer was able to measure the ...
How fast is light speed?Speed:Consider a kid running in the garden for a certain time duration and covers some distance during this time period. In this case, the speed of the kid can be given as the distance divided by the time duration and it is measured in meter per second....

One of them is Albert Einstein, a German physicist, who revolutionized our concepts of space and time with his theories of relativity. In 1905 Einstein published his special theory of relativity. The foundation of the theory is the observation that light moves at a constant speed as measured by...

Aperture refers to how much light is let into the camera sensor. Aperture is measured in "f-stops" (like f/1.8, f/2.8, f/16). A smaller f-stop number indicates a larger aperture (more light is allowed in), while a larger f-stop number means a smaller aperture (les...
