i was studying incidence of EM wave at a plane dielectric boundary and encountered equations(adsbygoogle = window.adsbygoogle || []).push({});

in the attachment . I just want to know if n2 > n1 then electric field amplitude at the boundary increases . So from where does this extra value comes ?

n1 and n2 are intrinsic impedances of 1st and 2nd medium
