Light arriving at drip
light refraction occurs, because the moves through an intermediary with different density (from air to water) by
light blue over red light refraction
.The light reflection inside the drip because of the internal surface of the droplet. With the curve and surface khlaikrachok
light refraction occurs. Water drips from the inside through to the air again.
When you look at the overall view of the red light reflex is a reflex angle 42 degrees, while the light blue is 4 degrees
