A musician uses a tuning fork of frequency f = 245 Hz to tune his guitar and his trumpet. There is a beat frequency between the tuning fork and the guitar string and between the tuning fork and the trumpet for this note of fbeat = 4 Hz. a. Determine the ratio L' / L between the length of the air column before tuning L and the length of the column once it is tuned L' to eliminate the beat frequency.  b.  If the original length L is 150 cm, what must be the new length L' in m?

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
