@astro_physiccs: Blue is scattered more than other colours because it travels as shorter, smaller waves. However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light. #universe #space #science #knowledge #physics #astronomy #planet #solarsystem #khoahoc #kienthuc #forpage #earth #sunset
