@astro_physiccs: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down. #space #universe #khonggian #earth #solarsystem #knowledge #gravity #science #distances #vutru #physics #xuhuong #astronomy #astrophysics
