SAT Subject Physics Practice Question 306: Answer and Explanation
2. The diagram below shows a set of open-ended pipes with waves vibrating inside them.
Which of the diagrams shows the pipe containing the waves with the highest frequency?
Correct Answer: E
The correct answer is (E). There are 4 waves in the pipe, which means the wavelength is much shorter that it is in diagram B. Frequency is the inverse of wavelength so as the wavelength decreases the frequency increases.
