What is a sound wave in physics?
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound.
What is sound wave in short answer?
In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
What is sound wave and its type?
Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Keep reading to find out what qualifies them as such. Longitudinal Sound Waves – A longitudinal wave is a wave in which the motion of the medium’s particles is parallel to the direction of the energy transport.
What is sound wave with example?
“Sound is a form of energy that is passed from one point to another as a wave.”Sound is an example of a longitudinal wave….Sound intensity level.
| Sources of sound | Intensity (W m-2) | Intensity level(dB) |
|---|---|---|
| Vacuum cleaner | 10-5 | 70 |
| Mosquito buzzing | 10-8 | 40 |
| Whisper | 10-9 | 30 |
| Rusting of leaves | 10-11 | 10 |
What is sound in physics Brainly?
Sound is produced when the particles of a system vibrate back and forth about their mean position. It is a form of mechanical wave. Brief Explanation. Sound waves need a medium to travel. The medium can be solid, liquid or gas.
What is sound wave Class 9?
Sound waves are longitudinal waves. Sound waves are produced due to variations in pressure & density of the medium. Compression is the portion of the medium where a temporary increase in volume & a decrease in density takes place when a sound wave passes through the medium.
What is sound wave Class 11?
Sound waves are mechanical longitudinal waves and require medium for their propagation. Sound waves can travel through. [sound waves cannot propagate through vacuum. If Vs, Vi and Vg are speed of sound waves in solid, liquid and gases, then. Vs > Vi > Vg.
What are sound waves made of?
When you bang a drum its skin vibrates. The harder you bang, the bigger the vibrations. The vibrating drum skin causes nearby air particles to vibrate, which in turn causes other nearby air particles to vibrate. These vibrating particles make up a sound wave.
What is meant by sound answer in Brainly?
Answer: 1. vibrations that travel through the air or another medium and can be heard when they reach a person’s or animal’s ear. “light travels faster than sound”
