Stationary waves are the result of _ waves travelling in opposite direction.
Correct answer: D. Identical
- A. Different
- B. None of these
- C. Stationary waves cannot be formed
- D. Identical
Explanation
A standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. It is formed by two waves traveling in opposite direction. It is necessary for the two waves to be identical (have the same wavelength and amplitude) for them to add up into a single stationary 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.
