#DidYouKnow: Sound travels slower through air than by water. In fact, the speed of sound via water is 4.3 times faster than by air. However, sound does travel far faster through steel than both air and water.

yeah in water, the molecules are more closely packed whereas in steel, the particles are more closer, making the vibrations of sound travel faster than water and air
@@sejalpatel8800 yes I also want to know that cuz we have this same exercise in our physics book,they might ask this question in my test,does it has anything with cardboard being a good producer of sound?
Waves don't enter a wall because they are good reflectors of sound. While some substances such as woollen clothes, thread etc. These are the bad reflectors of the sound so they cannot allow the light to pass through it. They are good absorbers of sound.
Given resonance distance of a sound wave is 75 feet. It has been noted that various pundits give contradictory figures. The 75 feet can be checked by stretching a string 75 feet and plucking it. Lengthening the string results in a weaker and slower sequence of clicks.
Hi Vikram. Here is a link bit.ly/DontMemoriseRU-vid for English channel .Where you can see our all our English videos and by seeing them you can clear all your doubts. 🙂🙂
You're most welcome. We are really happy to hear that it was helpful to you. We are glad that you understood the concept. You motivate us to do better. Keep watching our videos : )
wave transfers some of its energy to wall but the wall cannot move up and down like a wave as it is denser than the medium in which sound is travelling (air) thus the wall exerts a backward force on the wave causing the wave to reflect back at 180 degrees or pie radians.
@@lavaakshikeote But miss sounds also travel in solids the reason is that when the molecules move at last their energy get low and hence their sound is not travel through 🙂🙂😌

@@InfinityLearn_NEET ow.. Thank u for notify N obviously ur way of learning is so practical that no one can let u without subscribe N again its obvious to get notification bell on😊😊✌️
