Find the speed of sound in air at `23^(@)C`. (consider the speed of sound in air at `0^(@)C` is `331.3ms^(-1)`).

Speed of sound wave in air .

At 10^(@)C , how for away is a reflecting surface if you hear an echo in 0.274s? (speed of sound in air at 0^(@)C is 331.3ms^(-1) ).

Calculate the velocity of sound in air:

A steel wire has a length of 12.0m and a mass of 2.10kg. What should be the tension in the wire so that speed of a transverse wave on the wire equals the speed of sound in dry air at 20^(@)C= 343ms^(-1)

A train standing at the outer signal of a railway station blows a whistle of frequency 400Hz in still air. (i) What is the frequency of the whistle for a platform observer when the train (a) approaches the platform with a speed of 10 ms^(-1) . (b) recedes from the platform with a speed of 10ms^(-1) ? (ii) What is the speed of sound in each case? The speed of sound in still air can be taken as 340ms^(-1) .

On increasing the temperature, the speed of sound in air:

The speed of sound in air is 331 ms^(-1) at __and__ at 22^circC .

The velocity of sound in solid is …………… than the velocity of sound in air.
