Decibels are the units that are used to measure amplitude of sound waves.
<h2>Further Explanation
</h2><h3>Waves </h3>
- Waves are a transmission of a disturbance. They involve transmission of energy form one point called the source to another.
- Waves can be classified as either transverse waves or longitudinal waves
<h3>Transverse waves </h3>
- A transverse wave is a wave in which the vibration of particles if perpendicular to the direction of wave motion.
- Transverse waves contains regions of maximum displacement called crests and regions of minimum displacement called troughs.
- Examples of transverse waves are x-rays, radio waves, etc.
<h3>Longitudinal waves </h3>
- Longitudinal waves are types of waves in which the vibration of particles is parallel to the direction of wave motion.
- Longitudinal waves contains regions of minimal displacement of particles called compressions and those of maximum displacement of particles called rarefactions.
- Examples of sound waves include sound waves.
<h3>Sound waves </h3>
- Sound waves are examples of longitudinal waves.
- In addition sound waves are mechanical wave as they require a material medium for transmission.
<h3>Amplitude in sound waves
</h3>
- Amplitude in sound waves refers to the extent to which particles of air are displaced normally experienced as the loudness of sound.
- The loudness of a sound wave corresponds to the amplitude of the wave and is measured in decibels.
<h3>Frequency of sound wave
</h3>
- Frequency refers to the number of complete oscillations by particles in a wave in a second.
- Frequency of a sound waves determines the pitch of the sound. Frequency is measure in Hertz.
