Answer

Explanation:

Step1: Understand constructive interference

In constructive interference of two waves with equal amplitude $A_1 = A_2=A$, the amplitudes add up.

Step2: Calculate resultant amplitude

The resultant amplitude $A_R=A_1 + A_2$. Since $A_1 = A_2 = A$, then $A_R=A + A=2A$.

Answer:

B. It is twice than the amplitude of each wave.
