Special Relativity: Time Dilation
The meanings of the symbols used in this simulation are as follows. L = Distance that light travels in a stationary state, (=ct｡) c = Speed of light (≒ 299,792,458 m/s) t｡ = The transit time … more

Correction of Near-sightedness & Far-sightedness
Focusing The light started from the object must have arrived exactly at one point on the retina to see things in detail. On the other hand, if the light from one point of the object is … more
