Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
![**Problem Statement:**
If a sound wave (which moves at 343 m/s at room temperature) has a frequency of 360 Hz, then what is the wavelength of this wave?
**Explanation:**
To find the wavelength of a sound wave, use the formula:
\[
\text{Wavelength} (\lambda) = \frac{\text{Velocity of Sound} (v)}{\text{Frequency} (f)}
\]
In this case:
- Velocity of sound (\(v\)) = 343 m/s
- Frequency (\(f\)) = 360 Hz
Substitute these values into the formula to calculate the wavelength.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2b632062-7ccc-4dd3-a093-b9e3993697da%2Ff9e0c93d-2300-4f6d-a4e6-36684d1545f8%2F2pdks4j_processed.jpeg&w=3840&q=75)
