k. i have a sun. it moves. by the angle we have a time. (i know it''s crude). now, how do i change the amount of reflection on the water by the time? does anyone know what conditions have to be met for water to reflect (otherwise it will be translucent and show what''s underneath) come on people, research sun theory (dont expect that term to come up in google ) blah help me blah M

All translucent materials have a refractive index. This is as follows:

n = speed of light in air / speed of light in medium
n = 1 / sin C

C is the critical angle. If light hits the interface between the two mediums (air and water) at an angle greater than the critical angle then it is reflected, rather than passing through the gap.

So there you have it, elementary physics!!


>>> EDIT >>>

Don't forget, angles are mesaured from the normal. The incident ray of light, normal, and reflected ray all lie in the same plane.

i completely forgot all about that, and i have a bloody exam on it in 3 days time.
