What is the energy contained in a 1.30 m3 volume near the Earth's surface due to radiant energy from the Sun

The energy contained is 5.856 x 10⁻⁶ J

Explanation:

Average energy density of electromagnetic radiation per unit volume is given by the equation;

²

where;

is permittivity of free space

is maximum electric field strength, this can be calculated from the intensity of sun reaching the Earth's surface.

The intensity of sun reaching the Earth is 1350 W/m²

Average energy density of electromagnetic radiation per unit volume;

The energy contained in a 1.30 m³ volume is given by;

E = (4.505 x 10⁻⁶)(1.3)

E = 5.856 x 10⁻⁶ J

Therefore, the energy contained is 5.856 x 10⁻⁶ J
