Question

The two waves shown here are the same distance from point X and are traveling toward each other.

What is the amplitude of the resulting wave when the two waves meet at point X?

0.0 cm
1.0 cm
2.0 cm
4.0 cm

Answer 1

The answer to your question is 0.0 cm

Answer 2

Figure missing to find amplitude

Here I try to explain, to find amplitude.

It is the maximum displacement of the wave. The resultant amplitude of two inferring waves is equal to sum of those two waves displacements at the same location. If they are in opposite direction destructive inference occurs.
