Question

The unit of intensity of sound is ______.

Options

• W

• `V/s`

• `W/m^2`

• `m/s`

Answer 1

The unit of intensity of sound is `bbunderline(W/m^2)`.

Explanation:

Sound intensity is defined as the amount of sound power that passes through a unit area perpendicular to the direction of the wave. Since power is measured in Watts (W) and area is measured in square meters (m²), the standard International System (SI) unit for sound intensity is Watts per square meter `(W/m^2)`.
