Find the intensity of EMW wave?
Asked by rajuharan | 12th Mar, 2017, 07:40: PM
Intensity is the energy delivered per unit area per unit time.
Now, the energy transported by an electromagnetic wave is directly proportional to the square of the amplitude E2, of the wave.
Hence, the intensity is
where c is the speed of light and μ0 is the permeability of free space.

- Why light can travel in vacuum where as sound can not do so
- What is polarisation
- how are frequency and intencity of electromagnetic wave related?
- Why a wave needs a medium to propagate? If so then why light does not need any medium? And why wave travel better in denser medium... and if so then why not light ?
