Why is it difficult to make an X-ray lens or mirror? Please give detailed answers thanks

Answer #1

It is difficult to make an X-Ray lens or mirror because
**X-rays are made up of very high energetic photons up to 100
keV (kilo electron volts) which requires 1-1.5 mm thick aluminium
sheet to stop / absorb it, while other particle like alpha, beta
just need few mm thickness of paper / cardboard to absorb
them.**

**From this observation we can conclude how energetic
these X-Ray photons are.**

**so, if we try to make X-Ray mirror, which needed to
reflect the X-rays, while these X-rays will tend to penetrate the
substance of mirror made and cannot be reflected back.**

**while in case of lenses which bends the incident light,
in case if X-rays the frequency is so high such that the rays will
pass undeflected and fails the working of X-Ray lens.**

**Therefore, it's very difficult to make X-Ray lenses and
mirrors.**

**Upvote, if the answer was helpful. Thanks & have a
nice day.**
