two wave pulses move toward each other along a rope. which diagram shows the resulting wave when they cross at point x?
Answer
Explanation:
Step1: Understand wave - superposition
When two wave pulses move toward each other and cross at a point, we use the principle of superposition.
Step2: Analyze the given pulses
The two wave pulses are identical in shape but moving in opposite directions. When they cross at point X, the displacements of the individual waves at that point add up. Since the pulses are in - phase (both are upward - going in the part that will cross), the amplitudes will add up.
Step3: Determine the resulting wave
The resulting wave will have an amplitude that is the sum of the amplitudes of the two individual waves at the point of crossing, creating a taller upward - going pulse.
