The diagram above shows two wave forms P and Q at a particular instant in time. the two waves will interface
Attached Figure / Diagram
A
destructively to produce a wave of larger amplitude
B
destructively to produce a wave of smaller amplitude
C
constructively to produce a wave of larger amplitude
D
constructively to produce a wave of smaller amplitude
Verified Correct Answer: C.
Physical Principles & Numerical Solution
In this case, since both waves P and Q are at positive displacements, they will interfere constructively.
Answer: C. constructively to produce a wave of larger amplitude.
