Note that the equation only works for small angle approximation. [br]Questions?[br]1. How will you increase the amplitude of the wave?[br]2. What are the factors that affect the frequency or Period of a wave?[br]3. What will happen to the frequency and period of a wave if we increase the length of the string of the pendulum?[br][br]Reference: Russel, Daniel (2018).
