SSC MTS EXAM

Detailed explanation-1: -Destructive interference occurs when the crests of one wave overlap the troughs of the other wave, causing a decrease in wave amplitude. When waves are reflected straight back from an obstacle, the reflected waves interfere with the original waves and create standing waves .

Detailed explanation-2: -What is Destructive Interference? Destructive interference occurs when waves come together so that they completely cancel each other out. When two waves destructively interfere, they must have the same amplitude in opposite directions.

Detailed explanation-3: -The crests of the two waves are precisely aligned, as are the troughs. This superposition produces pure constructive interference. Because the disturbances add, pure constructive interference produces a wave that has twice the amplitude of the individual waves, but has the same wavelength.
