Why are we unable to see x-rays? btw I know this is not math but I put it as math because if I put it as physics no one would see it ;-;

We are unable to see x-rays because x-ray light it is too blue for us to see.

Step-by-step explanation:

Too much blue light can cause retina damage to the eye or eye strain. Their are kinds of lens that help protect you from blue light. There are good things about blue light but this is why we can't see x-rays.

I hope this helps!
