The distance between two consecutive nodes or anti-nodes is:

Correct answer: C. λ/2

  • A. λ/4
  • B. λ
  • C. λ/2
  • D. 2λ

Explanation

Option C is correct.The distance between two consecutive nodes or antinodes is half of the wavelength. A node is a point on a standing wave where the displacement is zero. An antinode is a point on a standing wave where the displacement is maximum. The distance between two consecutive nodes or antinodes is half of the wavelength λ/2 because the wavelength is the distance between two consecutive points on a wave that is in the same phase.

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.
