Double Rainbows: What They Are and How to Make Them
What is a Double Rainbow?
A double rainbow is a rare optical phenomenon that appears as two rainbows. The primary rainbow is the result of the refraction and reflection of sunlight in rain droplets; the secondary rainbow is caused by a second reflection within the raindrops.
How to Make a Double Rainbow
To make a double rainbow, the sun must be behind you and the rain must be in front of you. The sun's rays must pass through the rain droplets at a specific angle to create a double rainbow. The best time to see a double rainbow is in the early morning or late evening, when the sun is low in the sky.
Here are some tips for making a double rainbow:
- Find a spot where the sun is behind you and the rain is in front of you.
- Wait for the sun to shine through the rain.
- Look up and see if you can spot a double rainbow!
