➠In the SI system, it has units watts per square metre.

Answer 2

Explanation:

What is intensity?

Intensity refers the measured amount of properties like force, magnetic field , brightness

Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m2.
