Document Summary
Red has the longest wavelength (l) and blue/violet has the shortest. It measures its value of the speed of light in different materials to the speed of light in a vacuum (n=c/v) A spearfisher is standing on the shore and observing a fish underwater. Bits are digital info composed of sequences of 0s and 1s. Baud rate (r) is the number of bits sent/received per second. Theory of information: computers and modern communication store and send information and signals in terms of the numbers 0 and 1. If you want to send the largest number of bits per second, you need the highest frequency signal you can conveniently. White light is a mixture of all colours of the rainbow. Tetrechromacy is possessing 4 types of cones, which increases # of detectable colours. Hyperspectral imaging: cameras that detect more wavelength bands than the human eye.
