WebSound is a vibration that travels through the medium in the form of longitudinal waves. This means that sound waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation. Sound waves are called mechanical waves since they require a medium to propagate. The medium can be solids, liquids or gases. WebClass 8 is one of the crucial stages in students’ academic life as it lays the foundation for the concepts taught in Class 10. Sound is produced by vibrating objects.

WebSpeed of sound depends on the properties of the medium: pressure, density and temperature Speed of sound: Solids > Liquids > Gases Speed of sound in air = 331 m/s at 0 0 C and 344 m/s at 22 ∘ C When a source emits sound with a speed greater than the speed of sound in air, it creates a sonic boom which produces shockwaves with lots of … WebSolution: We know that the speed of sound is given by the formula: v = λ ν. Substituting the values in the equation, we get. v = 0.35 m × 2000 Hz = 700 m/s. The time taken by the sound wave to travel a distance of 1.5 km can be calculated as follows: Time = Distance Travelled/ Velocity.
