Question

Two waves are travelling and superimposed as a result of this constructive interference occur between waves, the two waves amplitude are:

• A. added to produce a larger amplitude.
• B. subtracted to produce a smaller amplitude.
• C. added to produce a smaller amplitude.
• D. cancelled out by each other.
• E. in opposite directions.

Answer 1

The correct option is A added to produce a larger amplitude.

Constructive interference is the interference of two or more waves of equal frequency and phase, resulting in their mutual reinforcement and producing a single amplitude equal to the sum of the amplitudes of the individual waves.

The amplitudes of the two waves get added as $A_{resultant}=A_1+A_2$
