Question

Suppose that a space telescope has been designed that can produce sharp images in visible light. Then a proposal is made to redesign the telescope so that it has a considerably larger focal length but a considerably smaller aperture. Which of the following is an accurate statement of the advantages and/or disadvantages of the new design? Choose one: A. The telescope will be less able to detect dim objects. But it will be more able to resolve fine detail, especially when using light of longer wavelengths such as red and infrared. B. The telescope will be more able to detect dim objects, and it will be more able to resolve fine detail regardless of wavelength. C. The telescope will be able to detect dimmer objects, especially using light of longer wavelengths such as red and infrared. But it will be less able to resolve fine detail. D. The telescope will be less able to detect dim objects but it will be more able to resolve fine detail, especially when using light of shorter wavelengths such as the ultraviolet. E. The telescope will be able to detect dimmer objects, especially using light of shorter wavelengths such as violet and ultraviolet. But it will be less able to resolve fine detail. . F. The telescope will be less able to detect dim objects, and it will be less able to resolve fine detail, especially at longer wavelengths.

Answer 1

Answer:

F. The telescope will be less able to detect dim objects, and it will be less able to resolve fine detail especially at longer wavelength

Explanation:

The telescope will be less able to detect dim object due to it's small aperture and can't also resolve fine and bright image.
