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.
Q14
![**Question:**
Transverse waves propagate at 43.2 m/s in a string that is subjected to a tension of 60.5 N. If the string is 16.5 m long, what is its mass?
**Options:**
- A) 0.535 kg
- B) 0.621 kg
- C) 0.225 kg
- D) 0.38 kg
**Explanation:**
To solve this problem, use the formula for the speed of a wave on a string:
\[ v = \sqrt{\frac{T}{\mu}} \]
where:
- \( v \) is the wave speed (43.2 m/s),
- \( T \) is the tension in the string (60.5 N),
- \( \mu \) is the linear mass density of the string.
First, solve for \( \mu \):
\[ \mu = \frac{T}{v^2} \]
Calculate \( \mu \) using the given values:
\[ \mu = \frac{60.5}{(43.2)^2} \]
Then, calculate the mass (\( m \)) of the string using:
\[ m = \mu \times L \]
where \( L \) is the length of the string (16.5 m).
This will give you the mass of the string, matching one of the provided options.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffdac5784-6171-4c2d-813f-cbb526f56bfb%2F701c635c-7edc-485b-b500-20eea6273dc7%2Fi16f1xi_processed.jpeg&w=3840&q=75)
