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.

What is the difference between optical and radio?

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


How radio telescopes differ from optical telescopes.?

Radio telescopes collect radio waves. Optical telescopes capture visible light waves.


In what ways are radio telescopes better than optical telescopes?

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.
