Question

If there were two telescopes with the same diameter, but one is a visible light telescope and the other a radio telescope, how would the resolution of the images from each telescope compare? The wavelength of visible light is several hundred nanometers (1 nanometer = 10–9 meters), and radio can be several centimeters (1 cm = 10–2 meters) or several meters.

Answer 1

The radio telescope would have much better angular resolution.

Step-by-step explanation:

If you take a look at the electromagnetic spectrum, you will notice that radio waves has the longest wavelength, but shortest frequency and energy. So since the wavelength of the radio wave is higher, it will have a better angular resolution.
