Wave Interference — Quiz

Test your understanding of wave interference with 5 practice questions.

Practice Questions

Question 1

In a standing wave on a string fixed at both ends, what is the wavelength of the third harmonic?

Question 2

Two waves of the same frequency travel in the same direction and interfere. If the amplitude of the first wave is $A_1$ and the amplitude of the second wave is $A_2$, what is the maximum possible amplitude of the resultant wave?

Question 3

A wave on a string has a wavelength of $\lambda$ and a frequency $f$. What is the speed $v$ of the wave?

Question 4

A pipe open at both ends is resonating at its fundamental frequency. If the length of the pipe is $L$, what is the wavelength of the sound wave?

Question 5

Two waves traveling in the same medium have a phase difference of $\pi$. What is the resulting amplitude of the superposition if both waves have amplitude $A$?
