- Standing waves: A combination of two waves moving in opposite directions, each having the same amplitude and frequency are known as standing waves.
- Standing waves are produced when the guitar string is stretched.
The frequency of the wave is given by:
l is the length of wire, T is tension in the wire, μ is mass per unit length of wire.
EXPLANATION:
In the guitar wire, length l and mass per unit length μ will be constant.
So,
f ∝ √ T -- (1)
- From the above expression, frequency is directly proportional to the square of the tension.
- If stretching increases, that means we are increasing the tension.
- If tension increases, the frequency will increase.
- So, If you go on increasing the stretching force on a wire in a guitar its frequency increases.
