The presence of stationary waves on a string can easily be detected atI. nodesII. antinodes
Correct answer: C. I and II.
- A. I only
- B. II only
- C. I and II.
- D. between I and II.
Explanation
C) I and II.Here's why: * Nodes: Nodes are points on a stationary wave where there is no displacement, meaning the string remains motionless. This absence of movement is a very clear and easily detectable indicator of a stationary wave. * Antinodes: Antinodes are points on a stationary wave where the displacement is maximum. The large amplitude of oscillation at these points also makes them easily detectable and signifies the presence of a stationary wave.

About Stationary Waves
Stationary waves form when two waves of the same frequency and amplitude travel in opposite directions and interfere. The topic covers nodes, antinodes, wavelength, phase, resonance, and the allowed frequencies on strings and in air columns. Unlike progressive waves, stationary waves do not transfer energy from one point to another.
