What is the energy of cell phone radiation with 1m wavelength

Explanation:

Electromagnetic waves are oscillations of the electric and the magnetic field in a plane perpendicular to the direction of motion the wave.

All electromagnetic waves travel in a vacuum always at the same speed, the speed of light:

The energy of an electromagnetic wave is given by the equation:

where:

is the Planck constant

is the speed of light

is the wavelength of the wave

In this problem, we have a wave with wavelength of

So, its energy is:

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
