Simple Harmonic Pendulum (Small Angle Approximation)
SHM on Pendulums
Note that the equation only works for small angle approximation.
Questions?
1. How will you increase the amplitude of the wave?
2. What are the factors that affect the frequency or Period of a wave?
3. What will happen to the frequency and period of a wave if we increase the length of the string of the pendulum?
