⏩ The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day . . . . . #science #space #physics #light #lightart #viral #experiment #experimental #school #student #prism #chemistry #fact #laboratory #meme | Science_cosmo

(II) Below a certain threshold pressure, the air molecules (0.3 -nm diameter) within a research vacuum chamber are in the "collision-free regime," meaning that a particular air molecule is as likely to cross the container and collide first with the opposite wall, as it is to collide with another air molecule. Estimate the threshold pressure for a vacuum chamber of side 1.0 m at 20^∘ C . | Numerade
