Question

when two waves with opposite amplitudes (+ and -) travel toward each other and overlap, the resultant waves amplitude is ____.

the same as the original.

zero.

twice the original wave.

Explanation:

This question is about wave interference, a concept in Physics (subfield of Natural Science). When two waves with opposite amplitudes (e.g., one with +A and one with -A) overlap, they undergo destructive interference. The resultant amplitude is the sum of the individual amplitudes: \( A + (-A) = 0 \). So the resultant amplitude is zero.

Answer:

B. zero.
