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.

**Title: Sound and Light Synchronization at a Fireworks Event**
**Scenario:**
While attending a large fireworks event with music, you decide to stay 1 kilometer away because of the crowds. However, you have a good view, and you can still hear the booms, as well as the music. Given a speed of sound on a warm moist summer night of 340 m/s, evaluate the following statements and select those that apply:
1. \[ \square \] The music is out of phase with the fireworks and occurs about 3 seconds late.
2. \[ \square \] The booms are so loud they occur at the same time as the flash of fireworks explosion.
3. \[ \square \] The music has the wrong pitch with its frequency changed by the time it takes to reach you.
4. \[ \square \] The booms follow the flashes you see by about 3 seconds.
5. \[ \square \] The music is out of phase with the fireworks and occurs about 6 seconds early.
**Explanation:**
When observing fireworks from a distance, the speed of sound (340 m/s) causes a delay between the visible flash and the audible boom. For example, at a distance of 1 kilometer (1000 meters), the sound will take approximately 3 seconds to reach your ears. Hence, you would experience the visual flash of the explosion before hearing the corresponding sound.
