How are radio telescopes different from keck telescopes?

Keck telescopes do not exist, Keck telescope refers to the WM Keck Observatory on Mt. Kea.The Keck Observatory is comprised of several opticalreflecting telescopes, whereas aradio telescope consists of a large parabolic solid metal or screen reflector with a radioreceiver at its focus, built to detect and measure radio waves.


Is the design of radio telescopes very similar to the design of refracting telescopes?

No, radio telescopes and refracting telescopes have different designs and functions. Radio telescopes are designed to detect radio waves from space, whereas refracting telescopes use lenses to bend light to create images of distant objects. While both types of telescopes have a common goal of observing the universe, their designs are optimized for different wavelengths of electromagnetic radiation.
