D) X-ray radiation.

Question

Quizplus · Accepted Answer

Normal reflecting telescopes are designed primarily for visible light but can also be adjusted to detect infrared and near ultraviolet radiation. However, they cannot detect X-ray radiation effectively because X-rays do not reflect off mirrors in the same way as visible light, infrared, or ultraviolet radiation. X-ray telescopes require special optics, such as grazing incidence mirrors, to focus X-rays.
