Can anyone please prove that if d1=EF and if d2=EG(adsbygoogle = window.adsbygoogle || []).push({});

and angle MEZ=HEF=angle of incidence

and angle HEG = angle of refraction.

Please! can somebody help me prove that d1/d2=refractive index

taking sin i/sin r=refractive index

(The glass slab is ABCD and is kept in vacuum)
