Standing stationary waves can be obtained in an air column even if the interfering waves are
Text Solution
Verified by ExpertsThe correct answer is:
D
Standing stationary waves are formed when two waves of the same frequency and amplitude travel in opposite directions and interfere with each other. The key condition for stationary waves is that the waves must have the same frequency and wavelength.
Therefore, even if the waves move with different velocities, they can still generate standing waves provided they meet the frequency condition. Hence option D is correct because different velocities can still contribute to the formation of stationary waves in an air column.
