This will probably be a very basic question, but looking for a simple answers.
What I know
- the visible light is a form of electromagnetic radiation with a defined wavelength.
- the full spectrum contains radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
For the visible light exists many types of lenses and/or mirrors - where the refraction changing the direction of waves - e.g. focusing lenses, made of transparent material like glass.
Do such lenses exist for other types of electromagnetic radiation? E.g. Are there lenses for radio waves or for X-rays? What materials are they made of ? What about the mirrors (e.g. gamma ray mirror) ?
If such mirrors/lenses do not exist, then why not?
Can someone point me to some basic articles tolearn about this?
