1. The problem statement, all variables and given/known data Consider standing waves in an organ pipe. True or false: 1. In a pipe open at both ends, the frequency of the third harmonic is three times that of the first harmonic. 2. In a pipe open at both ends, the frequency of the fifth harmonic is five times that of the fundamental. 3. In a pipe that is open at one end and stopped at the other, the even harmonics are not excited. 2. Relevant equations 3. The attempt at a solution I got it as 1. False 2. False 3. True Are they right?
