Document Summary

Table of contents: electronic structure of atoms, chemical bonding. The interaction of atoms or molecules with light is well documented: Colour: light being reflected off surfaces or entities. Phosphorescent: glow in the dark, condoms, frisbees. Fields are perpendicular to the motion of the wave and to each other. possesses energy defined in formulaic form as: E= h carrying units of joules (j) Described in terms of: frequency = v a , wavelength = . Speed/velocity of light (c): c = x v h is planck"s constant, h = 6. 63 x 10-34 js. All radiations come in defined packets of energy. Quantum of light: photon, c is the velocity of light: 300 x 108 ms-1 in a vacuum. The unit s-1 = 1/s = reciprocal time = per second is given the special name hertz, abbreviated hz. 1 hz = 1 s-1 cycles per second.
