If the string vibrates in 'n' loops, the wavelength is given by:
Correct answer: B. λn = 2l/n
- A. λn = 2/nl
- B. λn = 2l/n
- C. λ= 1/2n
- D. None of these
Explanation
λn = 2l/nWhen the string vibrates in 'n' loops (higher harmonics), the wavelength is given by 2l/n, where 'l' is the length of the vibrating string.

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.

"Stationary waves" are so called because, in them,
With the increase in temperature, the frequency of the sound from an organ pipe
The fundamental frequency of a closed organ pipe is 50 Hz. The frequency of the second overtone is
If the successive overtones of a vibrating string clamped at its ends are 280 Hz and 350 Hz, the frequency of fundamental is:
If the number of loops of a stationary wave is increasing, then
A string of length 2m fixed between two supports vibrates in two loops. The distance between node and antinode is:
