प्रश्न
Answer briefly.
Wave motion is doubly periodic. Explain.
उत्तर
- A wave particle repeats its motion after a definite interval of time at every location, making it periodic in time.
- Similarly, at any given instant, the form of a wave repeats itself at equal distances making it periodic in space.
- Thus, wave motion is a doubly periodic phenomenon, i.e., periodic in time as well as periodic in space.
