The maximum magnitude of the magnetic field of an electromagnetic wave is 13.5 μτ. (3396) problem 3: 笄what is the average total energy density (in μ1m3) of this electromagnetic wave? assume the wave is propagating in vacuum.

The average total energy density of this electromagnetic wave is .

Explanation:

Given that,

Magnetic field

We need to calculate the average total energy density

Using formula of energy density

....(I)

Where, S = intensity

c = speed of light

We know that,

The intensity is given by

Put the value of S in equation (I)

Hence, The average total energy density of this electromagnetic wave is .

frequency or wavelenth of em radiation in a vacuum

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
