AI Generated Solution

To find the resultant amplitude of two sound waves with amplitudes of 4 cm and 3 cm, we will use the formula for the resultant amplitude when two waves interfere with a phase difference. The formula is given by: \[ A_R = \sqrt{A_1^2 + A_2^2 + 2A_1A_2 \cos(\phi)} \] where: - \(A_1\) is the amplitude of the first wave (4 cm), ...
