Please could somebody explain why the fundamental frequency always has the biggest amplitude in comparison to the rest of the harmonics?
pscience said:Two waves traveling in opposite direction should die out according to super position principle (Zero amplitude). Then how standing waves are produced? Is this not a contradiction? Please help. thank you.
The fundamental frequency is the lowest frequency of a periodic waveform. It is also known as the first harmonic and determines the pitch of a sound.
The fundamental frequency has the largest amplitude because it is the main frequency of a sound and contains the most energy. It is the foundation of the sound and all other frequencies are harmonics of the fundamental frequency.
The fundamental frequency is determined by the physical characteristics of the sound source, such as the length and tension of a string or the size and shape of a vibrating object. It can also be mathematically calculated by dividing the speed of sound by the wavelength of the sound wave.
Yes, the fundamental frequency can change depending on the properties of the sound source. For example, the fundamental frequency of a guitar string can be changed by altering its length or tension. Additionally, the fundamental frequency of a sound can be changed by using effects or filters.
Harmonics are integer multiples of the fundamental frequency. This means that the second harmonic is twice the frequency of the fundamental, the third harmonic is three times the frequency, and so on. The fundamental frequency and harmonics create a series of related frequencies that make up a sound wave.
