@spacex3321: When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line. #astrophysics #xh #vutru #xuhuong #Science #knowledg #scienceexperiments
