  • It's AumSum Time.

  • How do x-rays work?

  • It's confidential.

  • No.

  • X-rays are very high energy waves.

  • They were accidentally discovered by a physicist named Wilhelmntgen.

  • As he did not know what they were, he named them ''X-rays''.

  • X-rays can pass through many objects.

  • But if an object's density is more, then these rays get absorbed and don't pass.

  • Due to this property, X-rays are used to detect fractures, tumors, etc.

  • To detect a fracture, X-rays are passed through our body which then hit an X-ray detector or a photographic film.

  • Now, since our tissues are not dense enough.

  • Much of the X-rays pass through them and get detected by the film.

  • Thus casting a dark or grey shadow on the film.

  • But as the bones are much denser, the rays get absorbed and hence, the bones appear white on the film.

  • This allows doctors to have a look at the structure of bones and thus, spot the fracture.

It's AumSum Time.
