prove that i=e with Snell's law
Answers
your question is wrong
sin i/ sin r = constant..
Perhaps this will help, if you are looking at a non Calculus approach.enter image description here Consider two parallel rays A and B coming through the medium 1 (say air) to the medium 2 (say water). Upon arrival at the interface L between the two media (air and water), they continue their parallel course in the directions U and V respectively.
Let us assume that at time t=0, light ray A arrives at the interface L at point C, while ray B is still shy of the surface by a distance PD. B travels at the speed v1=cn1 and arrives at D in t seconds. During this time interval, ray A continues its journey through the medium 2 at a speed v2=cn2 and reaches the point Q.
We can formulate the rest, geometrically (looking at the parallel lines) from the figure. Let x denote the distance between C and D.
xsin(θi)xsin(θr)======PDv1tcn1tCQv2tcn2t
Thus,
n1sin(θi)n2sin(θr)==cxtcxt
Re arranging this will take us to the Snell's law as we know.
n2n1=sin(θi)sin(θr)
