Sunrise over Tomahawk Beach

Recently, there have been some extremely lovely sunrises here in Dunedin. While I don’t know the exact science behind what causes a colourful sunrise, I believe it’s all to do with light beams coming into the earth’s atmosphere and hitting molecules. Then, something happens with blue lightwaves becoming shorter while red, orange and yellow lightwaves become longer while moving through the atmosphere. Of course, I could always be completely wrong!
