In a standing waves, the distance between two consecutive nodes is which of the following?
Correct answer: C. Equal to half of wavelength
- A. Equal to one wavelength
- B. Equal to two wavelength
- C. Equal to half of wavelength
- D. Equal to quarter of wavelength
Explanation
Option C is correct since A standing wave pattern always consists of an alternating pattern of nodes and antinodes. Nodes and antinodes are the points known to form 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 λ/2.Note:Nodes and antinodes points should not be confused with crests and troughs in a wave.

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.
