We see and use light every day, but have you ever wondered what is light? Why can we see colors? And how did God use light at the very beginning?We’re exploring how light travels in waves and photons, why objects bounce colors into our eyes, and even how creatures glow using living light (bioluminescence) and reflective light (biofluorescence).
