A wave of amplitude 0.30 m interferes with a second wave of amplitude 0.16 m tra

Question

A wave of amplitude 0.30 m interferes with a second wave of amplitude 0.16 m traveling in the same direction.

(a) What is the largest resultant amplitude that can occur, and under what conditions will this maximum arise?
m

The two waves interfere constructively. The two waves interfere destructively.    

(b) What is the smallest resultant amplitude that can occur, and under what conditions will this minimum arise?
m

The two waves interfere constructively. The two waves interfere destructively.    

Explanation / Answer

a) A = A1+A2 = 0.46 m The two waves interfere constructively

b) A =A1-A2 = 0.24 m The two waves interfere destructively.
