Must have been someone who was unfamiliar with the expression 'figures

You reckon Eugene Hecht was lying when he shows us how to
add two irradiances to obtain the total irradiance (power
per unit-area) in _Optics_? Adding EM wave powers during
interference is a well accepted way of handling EM wave
superposition in the field of optics. The bright constructive
interference rings contain more power than the dark destructive
interference rings. RF waves and light waves are both electro-
magnetic waves, just at different frequencies. Asserting that
RF waves obey a different set of laws of physics than do light
waves is naive ignorance at best.
