eTwinning project "Inside the rainbow", by Rangel Pantaleev

Exploring the rainbow

2. Where we can see more rainbows?
The Earth is the only planet, where rainbows are possible.

3. Each raindrop makes its own rainbow but it needs
millions of raindrops to see the rainbow.

4. Very rarely light can be reflected 3 or 4 times
within a water droplet which produces even fainter
tertiary(third) and quaternary(fourth) rainbows in the
direction of the Sun.
You can see more rainbows in tropical locations and
by waterfalls.

5. Can we see the rainbow at night?
Yes, we can. A moonbow (lunar
rainbow or white rainbow), is a
rainbow produced by moonlight
rather than sunlight. It is caused
by the refraction of light in many
water droplets, such as a rain
shower or a waterfall, and is
always positioned in the opposite
part of the sky from the moon
relative to the observer.
