How does reflection & refraction enable astronomers to build telescopes and how is different for the 6 types?
What is the difference between reflection and refraction. How do these enable astronomers to build telescopes? Do these principles work equally well for all six types of telescopes and how?
(The telescopes built to view each region of the electromagnetic spectrum?)
Hi Reflection is when light bounces off a reflective surface, usually metal coated glass. Refraction is caused by light traveling through a surface at an angle. Steeper angles produce more bending of the light. The rest of your question relates to how well other parts of the spectrum would respond to these properties. Not well I’m afraid. X-rays for instance need an extremely close angle of incidence to reflect. (Look up ‘Chandra’). Radio waves use metal reflectors etc. Hope this helps.
