Which of the following could be a correct description of how light travels through a telescope? Light rays come in parallel to each other through an opening the telescope, are reflected by a curved primary mirror, focus onto a secondary mirror, then exit a. acBook ProExplanation / Answer
8] Option E is correct.
Refracting telescopes is more common than reflecting telescopes because refracting telescopes is used in the photography and reflecting telesccopes is used in astronomy.
