3. Assume the slab is perfectly rectangular and has width W.
(a) Calculate the distance (L) the light travels INSIDE the block as a function of W and the angle t1.
(b) From the right-angled triangle with vertices IPE calculate the lateral displacement x in terms of the incident and reflected angles and the width of the sample.
(c) If the incident angle is 60 degree, n=1.81, and W= 8.0 cm, what is x?
They mentioned Snell's law and how transmitted ray is parallel to the incident ray. n1sin(O1)=n2sing(02) 0=delta or whatever the circle with a little curve on the top is called. a diagram is attached.
