Sound has a huge impact on our day to day lives. Just think of how much of our technology involves sending or receiving sounds in various forms. Most people don’t fully understand what sound is. In this section we will be looking at the basic properties of sound. Sound is a longitudinal wave.

Sound travels in waves and is caused by vibrations. Sound travels fastest through solids, slowest in gases and at an intermediate speed through liquids. Bats and insects use a sound detection system known as echolocation to navigate their way through their environments. Echolocation is an example of a specialized sound detection system.

Amplitude is the size of the vibration. In human perception terms, this determines how loud the sound is. The larger the vibrations of a sound, the louder humans perceive it. Amplitude is measured in decibels (dB) Main Components of a Synthesizer Sound begins with the vibration
Sound must travel through matter because it needs the vibration of molecules to propagate. Because outer space is a vacuum with no matter, it's very quiet. The matter that transports the sound is called the medium. Speed of Sound The speed of sound is how fast the wave or vibrations pass through the medium or matter.
The Basic Properties of Sound Essay; ... The first film with basic sound showed up in the year of 1900 in Paris. Though the technique is quite juvenile, it is indeed a breakthrough in the film history. The first film with synchronous sound, which is actually the real sound film as we recognized, is ‘The light of New York’ published at 1928 ...
In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Humans can only hear sound waves as distinct pitches when the frequency lies between about 20 Hz and 20 kHz.

The basic properties of light are its wavelength, frequency, energy and speed. Light is composed of energy particles called photons and can behave as either a wave or as separate particles. The wavelength and frequency of light determine where the light is located along the electromagnetic spectrum.
