Due to the overlapping of two identical waves, the speed of the resultant wave:
Correct answer: C. Remains the same
- A. Decreases
- B. Increases
- C. Remains the same
- D. May increase or decrease:
Explanation
When two identical waves overlap, they interfere constructively or destructively, depending on their phase relationship. However, the speed of the resultant wave is determined by the medium through which it travels, not by the interference of the waves. Therefore, the speed of the resultant wave remains the same as the speed of the individual waves.

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.
