Imagine holding your hand in front of your face, and then slowly moving it away until you can see everything around you. That's sort of like how a wide-angle lens works!
A regular camera lens only captures a small part of what you can see, like looking through a tiny window. But a wide-angle lens lets you see more of what's around you by capturing a wider angle of vision. It's like looking through a bigger window that lets you see more.
This can be great for taking pictures of big landscapes or group photos, because you can fit more in the frame. However, sometimes it can make things look a little bit distorted or stretched out, especially things that are close to the lens.
Overall, a wide-angle lens is just a tool that helps you see and capture more of the world around you in your photos!
