Final answer:
The resolution of a telescope depends on the wavelength used, the size of the main telescope objective lens or mirror, and the design of the telescope.
Step-by-step explanation:
The resolution of a telescope depends on several factors. One important factor is the wavelength used and the size of the main telescope objective lens or mirror.
Shorter wavelengths can resolve smaller objects, resulting in higher resolution. Additionally, a larger objective lens or mirror can gather more light, improving the resolution.
Another factor is the design of the telescope. Different designs, such as reflector or refractor telescopes, can affect the amount of diffraction and therefore the resolution.
