The magnitude of the Poynting vector of a planar electromagnetic wave has an average value of 0.939 W/m2. The wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. How much total electromagnetic energy falls on the area during 1.0 minute

The  total energy is  

Explanation:

From the question we are told that

    The  Poynting vector (energy flux ) is  

    The length of the rectangle is  

    The  width of the rectangle is  

    The time taken is

The total electromagnetic energy falls on the area is mathematically represented as

Where A  is the area of the rectangle which is mathematically represented as
