Unit 2: Waves and Acoustics Chapter 15: Oscillations University Physics Volume I Unit 2: Waves and Acoustics Chapter 15: Oscillations Conceptual Questions 1. What conditions must be met to produce SHM? Solution The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation does not depend on the amplitude. 2. (a) If frequency is not constant for some oscillation, can the oscillation...

Conceptual Questions 1. Which of the following substances are fluids at room temperature and atmospheric pressure: air, mercury, water, glass? Solution Mercury and water are liquid at room temperature and atmospheric pressure. Air is a gas at room temperature and atmospheric pressure. Glass is an amorphous solid (non-crystalline) material at room temperature and atmospheric pressure. At one time, it was thought that glass flowed, but flowed very slowly. This theory came from the observati...

Unit 2: Waves and Acoustics Chapter 16: Waves University Physics Volume I Unit 2: Waves and Acoustics Chapter 16: Waves Conceptual Questions 1. Give one example of a transverse wave and one example of a longitudinal wave, being careful to note the relative directions of the disturbance and wave propagation in each. Solution A wave on a guitar string is an example of a transverse wave. The disturbance of the string moves perpendicular to the propagation of the wave. The sound produced b...
