my book is only introductory and they only gave me the equation S = t*sin( theta1 -theta2)/cos(theta2), i like to know how its derived so i can better understand and memorize this... i know i can probably work this out myself but i dunno where to start(adsbygoogle = window.adsbygoogle || []).push({});

i am assuming it has something to do with snells law and trig, but im bad at those
