can you please explain intensity and the relation between intensity and wavelenth?

 

 

The intensity of an electromagnetic wave refers to the power per area a wave would impart should it be incident on a surface. The intensity is determined by the strength of the magnetic and electric fields

remember:

The amount of radiation emitted from a body increases exponentially with a linear rise in temperature

The average wavelength of electromagnetic emissions becomes shorter with increasing temperature

But the amount of radiation passing through a specific area i.e intensity  is inversely proportional to the square of the distance of that area from the energy source
