Waves

The ratio of the frequencies of the fundamental harmonic produced by an open pipe to that of a closed pipe having the same length is:

  1. A.1 : 2
  2. B.2 : 1✓
  3. C.1 : 3
  4. D.3 : 1

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
