What is sound in science?

Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

What is sound short answer?

Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound.

What are sound waves answer?

A sound wave is a mechanical wave. A sound wave is a means of transporting energy without transporting matter. Sound can travel through a vacuum. A sound wave is a pressure wave; they can be thought of as fluctuations in pressure with respect to time.

What are sound waves Class 9?

Sound is a mechanical energy which produces sensation of hearing. Sound is produced due to vibration of different objects. • Sound wave propagates as compressions & rarefactions in the medium. Sound waves are longitudinal waves.

What are sound waves made of?

Sound waves are composed of compression and rarefaction patterns. Compression happens when molecules are densely packed together. Alternatively, rarefaction happens when molecules are distanced from one another.

What is a sound landform?

In geography a sound is a large sea or ocean inlet larger than a bay, deeper than a bight, wider than a fjord, or it may identify a narrow sea or ocean channel between two bodies of land (see also strait). There is little consistency in the use of ‘sound’ in English-speaking cartography.

What is sound Ncert?

Answer. Sound is a form of energy which produces hearing sensation in our ears. Sound is produced by vibration of an object. When an object vibrates, it forces the particles of medium around it to also vibrate. They cause the neighboring particles to vibrate and so on.

What is a sound wave?

Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur- rounding medium (typical air) in vibrational motion, thus transporting energy through the medium.

What is sound and how does it work?

What Is Sound? Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur- rounding medium (typical air) in vibrational motion, thus

What is the pathway of a sound wave?

Pathway of a Sound Wave 1. The sound waves arrive at the pinna (auricle), the only visible part of the ear. 2. Once the sound waves have passed the pinna, they move into the auditory canal (external acoustic meatus) before hitting the tympanic membrane (eardrum).

Is sound wave a longitudinal wave?

Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur- rounding medium (typical air) in vibrational motion, thus. transporting energy. through the medium. Since the particles are moving in parallel direction to the wave movement, the sound wave is referred to as a. longitudinal. wave.
