Question 363

Why doesn't light go through the other side of a water droplet, refracting as it goes through, rather than reflecting back?
Actually, 96% of the light hitting the "other side of a water droplet" does pass out of the droplet. What you see in the rainbow is the 4% that reflects back from the far side of the water droplet. If all of the light reflected, the rainbow would be much brighter.
