Lead (Pb - for Plumbum) will block X-rays. It doesn't make things invisible, i.e., if an object is wrapped in Lead, the shape of the object would be visible.
The object becomes invisible from low power to high power because the focus of lens are different. So though the image is intensified the rays don't fall on the retina unless the distance is corrected.
If I would be invisible, I will do what ever I want.
If I had the power to become invisible, my name would be Shadowcloak.
In Math, a line does not have any thickness. It is a mathematical concept.Technically no, since its meant to be a one dimensional object (meaning that it can be technically described by one numerical value). But then, a one dimensional object has zero thickness, therefore it would be invisible due to it infinitely small thickness. So a line by definition has no thickness, but all true lines are invisible.
If used in the context of "to be invisible" it is a verb. Hide can be used as a verb for invisible, as in "to hide from sight".
If you were completely and entirely transparent ("invisible"), your retinas would likewise be transparent, and you would be unable to see.
Theoretically if light reflected off you would be same as what it would be if you were not there and shadows did not form you would be invisible. Practically it is impossible.
If the number in invisible how would we know what it was?
Any object you can see reflects light. If it did not reflect any light it would be invisible. Similarly, no object is so reflective that it reflects all light. The proof that it absorbs light is that it increses in temperature as it is exposed to light.
i would say so because its technically a wedge and an inclined plane but others might disagree
It is fantasy, and not real. But my guess would be that he put the parcel in his invisible bag, thus making the parcel invisible.
Invisible would be an adjective; however, invisibly is an adverb because it is describing a verb.
