Final answer:
A disadvantage of radio telescopes compared to optical telescopes is limited image resolution. Radio waves have much longer wavelengths than visible light, making it harder for radio telescopes to resolve fine detail.
Step-by-step explanation:
A disadvantage of radio telescopes compared to optical telescopes is limited image resolution. Radio waves have much longer wavelengths than visible light, which makes it harder for radio telescopes to resolve fine detail in the images they produce.
A disadvantage of radio telescopes compared to optical telescopes is limited image resolution. Radio waves have much longer wavelengths than visible light, making it harder for radio telescopes to resolve fine detail.
Even the largest radio dishes on Earth cannot produce as much detail as small visible-light telescopes used in college astronomy labs. To overcome this limitation, radio astronomers have developed a technique called radio interferometry, which links multiple radio telescopes together electronically to improve image resolution.
