Notes
... All EM waves follow the relation v = f λ and since v = the speed of light = c, we have c = f λ. Visible light has λ = 400 to 750nm. The full range of frequencies for EM waves constitutes the EM spectrum. It is difficult to measure a speed as great as 3 x 108 m/s. Michelson made accurate measurement ...

... Using Plancks hypothesis Einstein explained the photoelectric effect. Experiments had shown that light shining on a metal surface caused it to emit electrons. For each metal there is a minimum frequency below which no electrons are emitted. Einstein assumed light travels in packets(photons) that ...
