A great TED-Ed video about bioluminescence, the ability for natural live to emit light.
Minutephysics looks at how polarised light in the cosmic microwave background (CMB) gave rise to the discovery of gravitational waves.
Simple demonstration of the photoelectric effect using different coloured filters to alter the frequency of light reaching a metal plate, and the current changes accordingly.
