 * 2. The reconceptualisation of the model of light led to an understanding of the photoelectric effect and black body radiation **
 * describe Hertz’s observation of the effect of a radio wave on a receiver and the photoelectric effect he produced but failed to investigate
 * perform an investigation to demonstrate the production and reception of radio waves
 * outline qualitatively Hertz’s experiments in measuring the speed of radio waves and how they relate to light waves
 * identify Planck’s hypothesis that radiation emitted and absorbed by the walls of a black body cavity is quantised
 * identify data sources, gather, process and analyse information and use available evidence to assess Einstein’s contribution to quantum theory and its relation to black body radiation
 * identify Einstein’s contribution to quantum theory and its relation to black body radiation
 * explain the particle model of light in terms of photons with particular energy and frequency
 * identify the relationships between photon energy, frequency, speed of light and wavelength: E=hf and c=fx
 * solve problems and analyse information using: E=hf and c=fx
 * identify data sources, gather, process and present information to summarise the use of the photoelectric effect in photocells
 * process information to discuss Einstein and Planck’s differing views about whether science research is removed from social and political forces
