Wave or particle
Does light behave like a wave, a stream of particles or both? Scientists at the University of Oxford are taking advantage of the particle-wave duality of light to carry out work developing exciting new technologies.
This activity is suitable for stretching the more able students as it goes beyond what is taught about light in the KS4 curriculum, but is useful for students who may go on to study physics at KS5. Students will apply their knowledge about wave behaviour to explain the results from Young's double slit experiment and get first-hand experience of how scientists use experiments to test hypotheses.
