A string of length "E" can maintain the stationary waves of wavelength "λ" given by:
Correct answer: A. λn = 2E/n
- A. λn = 2E/n
- B. λn = 2En
- C. λn = 2n/E
- D. λn = E/2n
Explanation
The general formula for the wavelength of the stationary wave in a string is: λn = 2E/n

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.
