Total reflection (IRR)?
I just looked on TRI Raindrops today. My teacher said that when the rays of light Enter The Air Drop collide with the surface and are reflected downward and to be refracted and dissemination. She stated that the drop-side acted as a concave mirror You reflected light. My question is that when the light rays come into the drop and strike Why Drop think? If not undergo refraction and move to the outside air?
ALWAYS TIR occurs when a ray of light passes from a denser medium to rarer medium.In this case, the angle of incidence is certainly more than the critical angle (which leads TIR ):.))
