Consider a simple harmonic oscillator function that corresponds to some vibration in the vertical direction: yh'] = 10 cos [ 2t] 31!] (a) what is the amplitude of vibration {in arbitrary units)? (b) what is the period of the vibration? (c) Use the information gathered in steps (a) through (d) to sketch a plot of disturbance y versus time t, showing at least two peaks and at least two troughs of the function, Make sure to label the tick marks on the horizontal and vertical scales. nrb units time [seconds] Question 5. (worth 5 points] Consider a vibration producing some wave. If the frequency of the vibration doubles in size, what happens to {a} the frequency (b) the speed {c} the wavelength (d) the amplitude of the wave it produces? Select answers to these questions from me following choices: I The size of the quantity doubles. I The size of the quantity is cut in half. I The size of the quantity doesn't change. I I don't know
