journey of the photon
Have you ever wondered why the sky is bright during the day? Have you noticed that the blue sky is not even? Do you know what a rainbow is and why we see it that way? These and other fascinating phenomena are closely related to light, more precisely to the particles that form light: photons. Let's follow the mapping of some photons sent out from different places in the Universe to the thin atmosphere layer that surrounds our planet, so as to understand their behaviour and some of the phenomena that they cause. But before, let's try to understand some things about this particle.
