On Tuesday 10th May, three Year 12 IB students attended ‘Quantum Day’ at Bangkok Patana School. Utsav, Veli and Renaka had the opportunity to complete experiments in which they observed light as a particle or a wave. The aim of the day was to decide whether light is a particle or a wave, following in the footsteps of physicists such as Einstein, Maxwell and Planck. All the students really enjoyed the day and had the opportunity to work with students from ten other International schools situated in Bangkok. All took away an added understanding of quantum weirdness and were left pondering whether light is particle, wave, both or neither.
