How are rainbows formed. I know it’s about refraction from water droplets, but shouldn’t you see many tiny rainbows instead of one big one.
In: Physics
Imagine the sky is a Giant LCD display.
Each water droplet is a pixel on the display. Its transparent when light passes straight thru it.
But if the light passes thru at an angle, it gets a colour/hue when you view it.
The droplets are stationary, but your perspective is different with respect to different droplets. Droplets at a certain area give off a certain color, to you. Droplets in another area, another color.
You can also see this effect when you view your LCD display at extreme angles. I think the phenomenon is called colorshift.
