Hint We should know that the speed of sound varies depending upon the temperature of the air through which the sound will move. With the wind, the sound will travel faster. Wind is the bulk movement of a mass of the air through space and also follows the principal which is no different than the train speeding along or even we can say a comet zipping through the space.
Complete step by step answer
We know that when we talk about sound, then we talk about the kind of wave that sound is composed of. The sound waves consist of particles which vibrate to transfer the sound waves from one place to another. These waves while travelling are affected by various atmospheric conditions. These atmospheric conditions include, temperature, pressure, humidity and various other factors.
We know that the speed of sound in air is 344 m/s at the temperature and the speed of sound in aluminium is 5100 m/s.
Hence the correct answer is option B.
Note We should know that the speed of sound varies depending upon the atmospheric conditions. The most important factor is the temperature. We can also say that humidity also has some effect on the speed of the sound. The speed of sound is much faster in the solid materials than the liquids and the gases. The speed of the sound wave is very much affected by the properties of the matter. The properties of the matter affecting the speed of sound are elastic properties of the medium and the density.
