rp 8 waves in solids

set up on a bench

a pulley with a mass on the end a string going across a wooden bridge passing through a vibration transducer and signal generator

the signal generator allows to

generate specific vibration frequency

at the correct frequency

there will be a standing wave due to resonance

to get wavelength

measure string from wooden bridge to vibration transducer

the wave speed doesn`t depend on wavelength or frequency but

length of string and amount of mass

if frequency is increased past a standing wave

half wavelengths will form

to calculate half wavelength wave length

measure same distance as before but this time divide by number of half wave lengths you have and multiply by 2
