Hello and welcome to mysteries of science. My name's Stevie and I'm the deputy editor of Science and Nature, the monthly magazine from the team behind the week junior.

And I'm Michael the Features Editor. On this podcast, we investigate weird events, strange creatures and mysterious places.

That's right. And today we're going to be investigating your mysteries. These are the

questions that you want us to find out the answers to. Yes, so join us and some expert guests as we

explore everything from rainbows to dynos. This is Mysteries of Science. So Michael, what's our

first question? So this question was sent into us on Apple Podcasts,

and it's where do rainbows and moonbows come from? That's a great question. So who should

we get to answer it? Well, given the question is all about weather phenomena, who better to speak to Dan

a weatherman? My name is Ada McGiven. I'm a weather presenter and meteorologist at the Met Office.

So my job is to try and predict the weather and then try to communicate that to the public and

let me know what the weather's doing at the weekend or further ahead on the

Met Office YouTube channel, the Met Office Facebook page, Twitter page, TikTok account and

occasionally on TV as well.

Welcome to the show, Aiden. Let's start with rainbows. We all have seen those colourful curves

in the sky, but where do they come from? I know it's got something to do with rain, but why does rain lead to rainbows?

A beam of sunlight is made up of all the colours of a rainbow, but when it's travelling through

the air, those colours combine to create white light. However, raindrops act like a colour

sorter, and because raindrops are heavier than the

air, as the beam of white light hits each raindrop, the beam of light slows down and some

colours slow down more than others. So red light travels faster through a raindrop compared with, say, violet light.

And because they're all travelling at different speeds through the raindrop,

they'll tend to bend and they'll all come out of the raindrop,
