What is a rainbow made of?From where do these colours come? |
|
Answer» Answer: Rainbows appear in SEVEN colors because water droplets break white sunlight into the seven colors of the spectrum (red, orange, yellow, green, blue, indigo, violet). You can only see a rainbow if the Sun is behind you and the RAIN in front. The main rainbow becomes VISIBLE at an angle of around 40" from the horizon. |
