Distance between two consecutive antinodes in standing wave is:
Correct answer: B. λ/2
- A. λ/4
- B. λ/2
- C. 2 λ
- D. 5λ/2
- E. 3 λ /2
Explanation
Distance between two consecutive antinodes in standing wave is λ/2, so option B is correct.Nodes and antinodes are known to generate the stationary waves. In a given stationary wave, the distance between any given two successive nodes or any two successive antinodes is always half of the wavelength. The distance between the two successive nodes is λ2 .

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.
