A sound is produced between two vertical parallel walls. the echo from one walls is heard after 2s while from the other 2s after the first echo. The speed of sound in the air is 340 m/s. A sound is produced between two vertical parallel walls. the echo from one walls is heard after 2s [...]

A pulse of sound wave travels a distance l in helium gas in time T at a particular temperature. If at the same temperature a pulse of sound wave is propagated in oxygen gas, it will cover the same distance l in time. A pulse of sound wave travels a distance l in helium gas [...]

The extension in a string, obeying Hooke’s law, is x. The speed of sound in the stretched string is v. If the extension in the string is increase to 1.5 x, the speed of transverse waves in it will be: is x. The speed of sound in the stretched string is v. If the extension [...]
