Question

An organ pipe of length 3.0 m has one end closed. What is the longest and next-longest possible wavelengths for standing waves inside the pipe?

Answer 1

The longest wavelength for closed at one end and open at the other is Y/4 where why is the wavelength - that is node- antinode the next possible wavelength is 3 y/4- node- antinode - node- antinode Y / 4 = 3 m. Y =12 meters the longest wavelength 3 Y/4= 3 m Y =4 meters 1/ 3 times as long
