Speed of sound = The square root of (the coefficient ratio of specific heats × the pressure of the gas / the density of the medium). The speed of sound equation is expressed as, As a result, the speed of sound is the maximum in solids and the minimum in gases. The higher the sound speed, the greater is the elasticity and the lower is the mass. The speed of sound in a given medium depends on the elasticity and density of that medium. The distance travelled per unit time by a sound wave travelling in an elastic medium is known as the speed of sound. It can only flow through a medium like air, water, or solid. Owing to the lack of particles to serve as a conduit, sound cannot move through the vacuum. When an object vibrates, for example, it passes energy to the surrounding particles, causing them to vibrate as well. It travels in energy waves from one molecule to another, and when it enters a person's ear, it can be easily perceived.
How many times does it vibrate in a minute?Ī stone is dropped from the top of a tower 500 m high into a pond of water at the base of the tower.Sound is a vibration or noise which travels through any medium. The frequency of a source of sound is 100 Hz. Find the ratio of times taken by the sound wave in air and in aluminium to reach the second child. One strikes the end of the rod with a stone. Two children are at opposite ends of an aluminium rod. What are the typical wavelengths of sound waves in air corresponding to these two frequencies? Take the speed of sound in air as 344 m s But thunder is heard a few seconds after the flash is seen, why?Ī person has a hearing range from 20 Hz to 20 kHz.
What is the time interval between successive compressions from the source?įlash and thunder are produced simultaneously. How are the wavelength and frequency of a sound wave related to its speed?Ĭalculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.Ī person is listening to a tone of 500 Hz sitting at a distance of 450 m from the source of the sound. In which of the three media, air, water or iron, does sound travel the fastest at a particular temperature?
