A string is made to vibrate at its third harmonic. The diagram shows two points P and Q at a particular instant in time. Which of the following compares the period of vibration of P and Q?

(The string is closed at both ends; P is just before the first maximum antinode and Q is at the next minimum antinode).

A. Period of P and Q is the same

B. Period of P and Q is different

Why is it A not B?

What property of a wave describes how often it occurs?

An oscillation is a regular, repeating motion that goes back and forth between two points. The most common type of oscillation is a sine wave you can see in a pendulum swing or a wave in the ocean. The period of oscillation is the time it takes to complete one cycle of motion. The amplitude of oscillation is the distance from the center point to the highest or lowest point of the wave. The oscillation formula is used to calculate the period, frequency, and amplitude of a wave. You can find equations, answers, and help online or use our math textbooks.
