Question

Two pulses are propagating on a stretched string as shown in figure. The plane of propagation of pulses are perpendicular to each other. When the two pulses overlaps the resultant displacement of any particle is

• A. Algebraic sum of the individual displacement due to each wave pulse
• B. Vector sum of the individual displacement due to each wave pulse
• C. Independent of the individual displacement due to each wave pulse.
• D. None of these

Answer 1

The correct option is B Vector sum of the individual displacement due to each wave pulse

When the two wave pulses overlaps the resultant displacement of any particle is the vector sum of the individual displacement caused by each wave pulse.
