Simple Harmonic Motion and Waves
If 100 waves pass through a medium in 20seconds and their wavelength is 6cm then the velocity is
0.5ms
-1
0.3ms
-1
1ms
-1
2.5ms
-1
Velocity = displacement / time So , 6/20 = 0.3ms

Simple Harmonic Motion and Waves
The time T of the simple harmonic motion of a mass m attached to a spring is given by
T = 2π √(k/m)
T = 2π √(m/k)
T = π √(k/m)
T = 2π √(m+k)
