Two waves of the same frequency and amplitude traveling in opposite direction along the same position are:
Correct answer: C. Stationary waves
- A. Electromagnetic waves
- B. Microwaves
- C. Stationary waves
- D. Sound waves
Explanation
When two waves of the same frequency and amplitude moving with the same speed in the opposite direction along the same path, these types of waves are known as Stationary waves.

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.
