Below is a graph of a displacement-time wave for a particle which is obeying simple harmonic motion.From the graph, estimate the time period, T, the amplitude, A, the frequency, f, and the angular frequency, 𝜔. [4]2. Sketch the wave resulting from halving the amplitude, and doubling the time period. [2]The acceleration resulting from simple harmonic motion is given by 𝑎(𝑡)= −𝜔2𝑥(𝑡)where 𝑥(𝑡) is the displacement as a function of time (the graph above), and 𝜔 is the angular frequency of the wave.3. Sketch the acceleration-time plot for the graph above. [4]
