In acoustics, the harmonics of a sound all have a higher frequency than the fundamental frequency. The fundamental frequency is the lowest resonant frequency that a sound generator produces.Know More
Harmonics are whole-number factors of the fundamental frequency. For example, the second harmonic has a frequency that is double that of the fundamental, while the third harmonic is triple the frequency.
Any object that vibrates at a regular frequency, such as a guitar string or the air in a brass instrument, generates a harmonic frequency structure.
Sound quality, or timbre, depends on the frequency and distribution of the harmonics, as well as the different media that give rise to these vibrations.Learn more about Optics & Waves
The speed of sound is dependent on the medium through which it is traveling. Under typical conditions, at sea level, sound travels 1,225 kilometers per hour, or 340.29 meters per second.Full Answer >
Although there are many reasons sound is important; a couple reasons are that it allows humans and animals to hear and communicate, and it is a primary component in the functioning of sonar equipment. Sound occurs in a variety of waves, which have different characteristics and produce different types of noises.Full Answer >
Frequency reuse is the practice of splitting an area into smaller regions that do not overlap so that each utilizes the full range of frequencies without interference. The introduction of this concept was a major step in the development of mobile phone technology.Full Answer >
A carrier frequency is a technical term used to describe a frequency that is generated by a transmitter such as a radio or radar transmitter. A carrier frequency is sometimes known as a resting or center frequency.Full Answer >
