derivation of an expression for the angle of deviation in a prism, in terms of [tex]\theta[/tex]a and [tex]\theta[/tex]g and A
Homework Equations
([tex]\theta[/tex]a - [tex]\theta[/tex]g ) + ([tex]\theta[/tex]a' - [tex]\theta[/tex]g' ) = D
A = [tex]\theta[/tex]g + [tex]\theta[/tex]g'
i get stuck trying to put [tex]\theta[/tex]a' into the terms the question states, anyone have an idea? thanks,
