Document Summary

Only four colours of lights were observed for hydrogen. Pass light through a prism, and it will be split into different wavelengths. Every element gives off a different emission spectrum. Chemcam -> laser analyzing composition of rocks. When excited with a source of energy, elements will give off light. Visible light is part of the electromagnetic spectrum. Gamma rays -> xrays -> ultraviolet -> visible spectrum -> infrared -> microwave -> radio. Frequency (v) = speed of light (c) / wavelength ( ) Energy (e) = hv = (hc)/ -> h is a constant. +/- are phases -> depending on which side of the line the wavelength is on -> it is a sin graph. No, but you need the correct instruments. 4 colours of wavelengths = 4 different energies of life. These wavelengths are not random with some trial & error, a relationship between them was found.
