Explanation:

Intensity in the context of waves is defined using the formula \(I=\frac{P}{A}\), where \(I\) is intensity, \(P\) is power, and \(A\) is the area. This formula shows that intensity is the power transmitted by waves to a unit area perpendicular to the waves. Work (\(W = F\times d\)) is related to force and displacement, and beats are related to interference of sound waves (difference in frequencies).

Answer:

power
