Question 23: Silence zone takes place in response to (Tag : Waves motion and sound sub-tag : interference )

Correct answer: B. Destructive

  • A. Constructive
  • B. Destructive
  • C. Beats
  • D. Resonance

Explanation

Explanation: A silence zone, or a node, is formed in a wave pattern due to destructive interference. In this case, two waves are out of phase and interfere in such a way that they cancel each other out at specific points, leading to a region of reduced or no amplitude.

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.
