Physics of a Rainbow
For simplicity purposes, let’s consider the raindrop round and the sun is emitting only one ray.
A sunray is really made up of many colors!
Those we can see are called the visible spectrum
REFRACTION
(Snell’s Law)
The white light is separating because as light enters, it slows down. Different colors refract differently
REFLECTION
REFRACTION AGAIN!!!
Incoming Ray of Sunlight
Refraction
Reflection and Magnification off
interior wall of rain
<40° Violet
42°Red
Angles are crucial (Snell’s Law)
Ta-Da!!!
QUESTION
• Why does the rainbow “disappear” when you get closer to it, making it impossible to find the pot of gold????
