Flash and thunder are produced simultaneously. But thunder is heard a fewseconds after the flash is seen, why? How does the speed of sound in air vary withrise in density of the medium? |

Answer» Flash and thunder are PRODUCED are produced simultaneously,but the flash is seen first and then the sound is heard.This is because the SPEED of sound in air is very LESS than the speed of light in air. Speed of sound in air : 334ms⁻¹ Speed of light in air : 3X10⁸ms⁻¹ With the increase in DENSITY of the MEDIUM, the speed of sound also increases. |
