Question:
For an electromagnetic wave travelling in free space, the relation between average energy densities due to electric $\left(\mathrm{U}_{\mathrm{e}}\right)$ and magnetic $\left(\mathrm{U}_{\mathrm{m}}\right)$ fields is :
Correct Option: 1
Solution:
(1)
In EMW, Average energy density due to electric $\left(\mathrm{U}_{\mathrm{e}}\right)$ and magnetic $\left(\mathrm{U}_{\mathrm{m}}\right)$
fields is same.
