Continuous regular and rhythmic disturbance in a medium resulting in periodic vibration of a source causes _ in a medium.
Correct answer: D. periodic waves
- A. complex wave
- B. stationary wave
- C. electromagnetic wave
- D. periodic waves
Explanation
Wave is in the form of a pulse which is set up by a single disturbance in a medium like the snapping of one end of a rope or a coil spring. Continuous, regular, and rhythmic disturbances in a medium result from periodic vibrations of a source which cause periodic waves in that 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.
