In this session of Astronomy 1, we delve into the fundamentals of light and its dual particle-wave nature, introducing the concept of photons. Explore why the sky appears blue during the day and turns red at sunset due to atmospheric scattering. We also investigate the composition of stars and interstellar gas, revealing that they are made of the same elements that exist on our planet. Join us on this cosmic journey to understand the intricate connections between light and the universe.
