These images show one of the large `VLT’ telescopes at the European Southern Observatory’s facility at Cerro Paranal, Chile. The place where the laser beam comes out (seen in the inset photo) is just out of sight off of the top edge of the large photo. Also note that if you look down the telescope tube (in the main photo), you can see the tube’s front-end structure. Imagine that this telescope had a flaw similar to the Hubble Space Telescope’s - its light-gathering element was shaped wrong. What problem would this cause for the telescope? Group of answer choices It would not be able to bring rays of light from a distant object to a focus. The imperfect shape would mean that it could focus rays of visible light, but not rays of light of any other wavelength. It wouldn’t be able to gather much light compared to the pupil of a human eye. It would mean that the telescope could only work if placed above the Earth’s atmosphere, like the Hubble telescope.
