Question

If a ringing bicycle bell is held tightly by hand, it stops producing sound. Why?

Answer 1

Hint: Sound is produced due to vibration of particles because of this vibration, a pressure wave is created. This pressure wave causes particles in the surrounding medium such as air, water or solid to have vibration motion.

Complete answer:
When we are ringing a bell in a bicycle, the bell creates vibration of particles in the medium.This vibration produces sound. As the particle vibrates, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear. The ringing bicycle bell does not produce sound when it is held tightly with hand because the vibrations are stopped and stopped and so the sound production stops.

Additional information:
-Sound travels fastest through solids. This is because molecules in solid medium are much closer together than in the case of liquid and gas, which makes the sound waves travel more quickly through solids.
-Sound travels faster in liquids than in gases because molecules are more tightly packed compared to the gases.
-The speed of the sound depends upon the properties of the medium through which it is passing. When we consider the properties of a gas, we see that only when molecules collide with each other can the compressions and rarefactions of a sound wave move about.

Note: It should be noted that sound requires a material medium to travel that is sound cannot travel through vacuum. Sound waves are the mechanical wave, that is it can be either longitudinal waves or transverse waves depending on the medium.
