instruments and harmonics

what is a harmonic or fundamental frequency

a harmonic or fundamental frequency is the lowest natural frequency we get and it is ½ of a wavelength

what is a stationary wave

A stationary wave forms when waves reflect back and overlap, interfering with each other to produce nodes and antinodes. Antinodes occur where the waves interfere constructively, and nodes occur where they interfere destructively. For a stationary wave, the original and reflected wave must have the same wavelength and frequency. but nodes are produced because waves aren’t always in phase this doesnt’t mean that the reason they destructively interfere is because they don’t have same wavelength and frequency otherwise a stationary wave wouldn’t be produced.

what is a node

a node is a point where there is 0 amplitude and is a result of destructive interference

what is a antinode?

a antinode is a point where there is maximum amplitude and a result of waves interfering constructively

example of a stationary/standing wave is a string explain how

when there is a string with fixed ends at both sides like a guitar the string will stay still unless force is applied when you pull on the string the waves move up and down the string until it hits the fixed end and reflects back the reflected wave overlaps with the original wave and if they have the same wavelength and frequency they interfere constructively and create a stationary wave .and this is a example of a stationary wave

what is the sound produced in a instrument from

in a instrument the sounds made are from all the harmonics joined together

what is the formula for the speed of a wave on a string

v = √(T/μ) v=speed t=tension μ=mass per unit length

what is resonance

resonance is when a object or system is vibrating at its maximum amplitude when its forced to oscillate at its natural frequency and this is called resonance
