Path of Light Through a Circular (Spherical) Raindrop
I need to draw an accurate diagram of a light ray's path through a circular raindrop.
-The angle of incidence is 25degrees.
-The radius is 4.15cm
-n of water is ~1.33
-n of air is ~1.000293
I can calculate the first angle of refraction, but I cannot calculate the angle at which the light ray reflects from the raindrop. It does not say how in my textbook . Where is the normal?
Snell's Law
nAsinA=nBsinB

angle of refraction:
B=sin-1((1.000293sin(25degrees))/1.33)=18.533
