Answer 1

## Step 1Constructive interference is a phenomenon that occurs when two waves meet in such a way that their crests and troughs align. This alignment results in the waves reinforcing each other, leading to a larger amplitude than either wave individually.## Step 2Option A is correct because when two waves interfere constructively, the resulting amplitude is indeed larger than that of a single wave.## Step 3Option B is also correct. For constructive interference to occur, the two waves must be in phase, meaning their crests and troughs align.## Step 4Option C is incorrect. This describes destructive interference, where the amplitudes of the two waves are subtracted, resulting in a smaller amplitude.## Step 5Option D is correct. In constructive interference, the amplitudes of the two waves are added together, resulting in a larger amplitude.## Step 6Option E is incorrect. This describes destructive interference, where the waves are out of phase, with one wave's crest aligning with the other wave's trough.
