Answer:
Constructive interference, Amplitude = 3 units
Explanation:
From the diagram you provided, it appears that the two waves are about to interfere. The type of interference (constructive or destructive) depends on the phase relationship between the two waves.
Phase Relationship: Both waves are in phase, meaning their peaks (positive amplitudes) and troughs (negative amplitudes) align. When waves are in phase and interfere, they produce constructive interference. This type occurs when the peaks of two waves add up, leading to a resultant wave with greater amplitude than the original waves.
Given that the wave on the left has a positive amplitude of 2 units and the wave on the right has a positive amplitude of 1 unit, adding these results in an amplitude of 3 units.
