Okay kiddo, let me try to explain sun rays in a way that would be easy for you to understand.
So, you know how when we go outside on a sunny day, we can feel the warmth of the sun on our skin? That warmth actually comes from something called sun rays. Sun rays are a type of energy that come from the sun and travel all the way to Earth.
Think of it like this: Imagine you are standing outside and your friend is standing really far away from you. You want to talk to your friend, but you can't just shout because your friend won't be able to hear you. So, what do you do? You use a telephone, right? The telephone lets your voice travel all the way to your friend's ear.
Sun rays work kind of like that too. The sun sends out energy called radiation, which is like a bunch of little waves that travel through space. These rays of energy travel all the way to Earth and they give us light and warmth.
But do you know what's really cool? Sun rays are actually different colors! That's why when we see a rainbow in the sky, it has all the different colors of the rainbow - red, orange, yellow, green, blue, indigo, and violet. Sun rays have all these colors in them, but we usually can't see all of them at once because they blend together.
So, the next time you go outside on a sunny day, you can remember that you are feeling the warmth of the sun's rays on your skin. And if you ever see a rainbow in the sky, you can remember that the colors in the rainbow come from different parts of the sun's rays. Cool, huh?
