What Is Wave MotionMost of us have seen the formation of ripples when a small stone (pebble) is dropped into a pond. The disturbances created by the stone in the water produces ripples which move outwards towards the shore of the pond. If you examine the…

What Is Sonic BoomWhen a body moves with a speed which is greater than the speed of sound in air, it is said to be travelling at supersonic speed jet fighters, bullets, etc, often travel at supersonic speed, and when they do so, they produce a sharp, lo…

What is Sound and How is it ProducedSound is a form of energy that produces the sensation of hearing in our ears. Frequency range of audible sound for human is between 20Hz to 20 KHzSound need Material to Travel: You have learnt in previous section that…

Human Ear Structure And FunctionWe have just learnt how sound vibrations from a source propagate through the air and reach our ears. Let us now discuss how our ears actually ‘hear’ these sound vibrations. The ear can be broadly classified into three par…

What Is UltrasoundThe sound waves having frequency higher than 20,000 Hz is called ultrasonic waves or ultrasound. Human beings cannot hear ultrasound. Dogs, bats and dolphins can hear ultrasound. For example bats and dolphins can hear sound waves havin…

Characteristics of Sound WavesSound travels in the form of a wave. Waves are characterized by three basic quantities. They are frequency, speed, and amplitude. Two of the main characteristics of sound are pitch and loudness, which in turn are determined …

Relation Between Wave Velocity, Frequency And Wavelength For A Periodic Wave\( \text{wave velocity}=\frac{\text{distance covered}}{\text{Time}\,\,\text{taken}} \) \( =\frac{\text{wave}\,\text{length}}{\text{Time}\,\text{taken}} \) \( \text{or v}=\frac{\l…

Analysing Sound WavesSounds are mechanical waves. They are caused by vibrating objects. The string of a guitar, the skin of a drum and a tuning fork, all of these vibrate to produce sound. The vibrating cone of a loudspeaker in Figure produces sound. Its…

Classification Of Wave MotionOn the Bases of Necessity of Medium RequiredMECHANICAL WAVES The wave which propagates only in a material medium are called elastic or mechanical waves. Example: Sound waves, Water waves (ripples), Waves on stretched strings,…
