Which type of waves are used for night vision apparatus?
What is the difference from lower sound waves and higher sound waves?
What are sound waves and how do they travel?
Sound waves are mechanical waves. So it needs badly a material medium. Air is one such medium. Through this medium sound gets traversed in form of longitudinal waves and not in transverse mode. Even the medium is water or even metal it has to traverse only in longitudinal mode. But in strings waves could be passed both longitudinally and transversely. Using Meld(e)'s string apparatus stationary waves are produced.
