A stationary wave is formed in a pipe which is open at both ends. If length of pipe is L, then what is the maximum possible wavelength of the wave?
Correct answer: A. 2L
- A. 2L
- B. 1/2 L
- C. L
- D. 3L
Explanation
Maximum wavelength is formed in 1st Harmonic, in which L = λ / 2. Therefore, λ = 2L. Hence, Option A is correct.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
