Due to the overlapping of two identical waves the speed of the resultant wave:
Correct answer: D. Remains same
- A. Decrease
- B. Increase
- C. Becomes velocity
- D. Remains same
Explanation
Due to the overlapping of waves the amplitude of wave may change but the speed of wave does not change. Speed of wave depends upon the nature of medium.

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.
