Document Summary
Day 1: 20/1/17 rutherford atom, wave properties, electromagnetic radiation, blackbody radiation. Rutherford atom: central core containing most of the mass and half of the charge of the atom surrounded by cloud of e- Did not explain why elements have different protes. Did not explain how chemical bonding occurred. Orbiting e- should have radiated energy and slowly plummeted into the core. Did not explain why different atoms of different give off light character when burned or when electricy passed through them (atomic emission) Wavelength () distance between 2 consecutive peaks or troughs in a wave (meters) Larger wavelength = smaller frequency inverse realtsnipip. V = constant m/s or ms-1 (speed or velocity) Frequency (v) # waves/ 1 sec or sec-1 in hertz (hz) Light waves: both electric and magnetic radiation. When passed through a prism makes rainbow. Roygbiv (only cause our eyes only pick up this. Long wavelength = low frequency / low energy.
