Who is Charles Darwin?

Darwin is the first of the evolutionary biologists, the originator of the concept of natural selection. His principal works, The Origin of Species by Means of Natural Selection (1859) and The Descent of Man (1871) marked a new epoch.

What is Visible light wavelength?

Visible light wavelengths are between 400 and 700 nanometers. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. When white light shines through a prism, the...
