Hi, now I will show you an illusion 3-D
An optical phenomenon where appears at the space
an object. The one here is a little pig.
Look! It is a real image. An image caused by the concave mirrors
If I try to catch it, in fact it is like a ghost !
Look! What a cool thing! With this light, it is possible to see the reflection.
If I use a LASER pointer. The reflection occurs too.
The LASER light stops on the pig.
Very interesting. And the pig is floating in the air!
Indeed, there are two concave mirrors. One with a hole in the middle.
And another mirror where the little pig is placed in its vertex.
Thus, if you want to learn more, click at the second video when available.
Thank you very much and see ya!!
