Question

Which object is vibrating when the following sounds are produced? The buzzing of a bee or mosquito.

Answer 1

Hint:Acoustics is a discipline of physics that studies mechanical waves in gases, liquids, and solids, including vibration, sound, ultrasound, and infrared waves. An acoustician is a scientist who works in the science of acoustics, whereas an acoustical engineer works in the subject of acoustics technology.

Complete answer:
Sound may be defined as a sort of mechanical energy created by vibrations. When an item or molecules on its particles vibrate, they collide with nearby air particles or molecules, causing them to move. This causes the new vibrating molecules to collide with the molecules around them, causing them to vibrate as well.

They clash with an increasing number of air particles in their immediate proximity. This sound wave movement, which resembles a chain reaction, continues until the molecules run out of driving energy, which normally takes a long time, and their vibrations are never zero, but gradually decrease as time goes.

Let's talk about the buzzing sound a mosquito makes. We've noticed that the sound is only heard when mosquitoes are flying, not when they're merely sitting. This indicates that the buzzing sound is caused by mosquitoes flapping their wings to fly, and so the buzzing sound is caused by the vibration of a mosquito's wings.

Hence, mosquitoes vibrate when sounds are produced.

Note:Vibration is a periodic back-and-forth motion of particles in an elastic body or medium that occurs when practically any physical system is moved from its equilibrium state and allowed to respond to forces that seek to restore balance. In physics, sound is a vibration that travels through a transmission medium such as a gas, liquid, or solid as an acoustic wave. Sound is the receipt of such waves and the brain's perception of them in human physiology and psychology. Ultrasound is defined as sound waves with a frequency greater than 20 kHz that are inaudible to humans.
