Waves In A Solid RPA

Question 1

Method

Answer 1

Produce standing wave in vibrating string by adjusting frequency which is created when string oscillates vertically
Use a ruler to measure the wavelength by measuring length across multiple waves and dividing by number of waves
To measure frequency time number of waves passing fixed point in 10 seconds and divide by 10
