Two periodic waves of amplitudes A1 and A2 pass through a region. If A1 > A2  the difference in the maximum and minimum resultant amplitude possible is

(a) 2A1

(b) 2A2​

(c)A1 + A2

(d)A- A2.

The correct answer is (b) 2A 

EXPLANATION: 

The maximum resultant amplitude = A₁ + A₂ and the minimum resultant amplitude = A₁ - A₂. Hence their difference = (A₁ + A₂) - (A₁ - A₂) = 2A₂
