A verify that a photon of an fm radio signal with a, Ask an Expert

Academics

A) Verify that a photon of an FM radio signal with a frequency of 100 MHz has an energy of about 4e-7 eV.

b) In a typical radio receiver , the antenna collects enough photons to push a current averaging (very rougly) 1 uA through a potential difference of (very roughly) 10mV. Roughly how many photons does the antenna have to absorb every second to drive this motion of electrons?
