Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
All mirages are optical illusions but all optical illusions are not mirages.
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
A optical zoom use the lenses to focus in on a subject, pretty much the same way binoculars work. Digital zoom magnifies the subject by enlarging in in the pic thru a digital process, this is not a true type of zoom.
The interiors of optical instruments are intentionally black to minimize reflections and stray light, which can interfere with the clarity and accuracy of the images produced. Black surfaces absorb light rather than reflecting it, reducing glare and enhancing contrast. This design choice helps improve the overall performance of telescopes, cameras, and other optical devices by ensuring that only the intended light contributes to the final image.
No matter what hand you do task with doesn't make a difference in the way you see optical illusions.
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
No they are not bigger then radio telescopes at all.
Not necessarily.
They are optical telescopes.
Yes, that is correct.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
ofcourse optical zoom..................
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
