A string phone is placed in a vacuum chamber and Cup A is struck with a rod. Statement 1: Sound cannot travel from Cup A to Cup B.
Statement 2: Vibrations cannot travel through vacuum.
The correct statement is :
(a) Sound and light both require medium for propagation
(b) Sound can travel in vacuum, but light can not
(c) Sound needs medium, but light does not need medium for its propagation
(d) Sound and light both can travel in vacuum.
Statement 1: Sound needs a medium for its propagation. Statement 2: Sound cannot propagate through vacuum as vacuum does not have particles which can vibrate.
Similar to sound, light can not travel in a vacuum.
Can sound travel through a vacuum?
