Question

What makes glass or water transparent (what is the scientific explanation for this)? Do you think it would be scientifically possible for a man to become invisible, or transparent? (Keep in mind that writers of science fiction have often turned out to be prophetic in their imagination!)

Answer 1

The fact that light can pass through glass or water makes them transparent. When light falls on an object, the light reflected from it makes it visible to us. If a device can be made that prevents light from reflecting off the human body, then the human body can be made invisible.
