Why do astronomers need different telescope designs to observe across the electromagnetic spectrum?
A)New telescopes incorporate new technology to increase their efficiency.
B)Telescopes have to adapt to the greater distortion of the atmosphere at shorter wavelengths.
C)Photons of different energy have different wavelengths,some of which are not accessible from Earth's surface and require different collection strategies.
D)Light pollution is worse at radio wavelengths than visible wavelengths.
E)Astronomers and engineers enjoy the challenge of making new telescope designs.

Question

Quizplus · Accepted Answer

Photons of different energy have different wavelengths, and some wavelengths are not accessible from Earth's surface. Therefore, different collection strategies are required. Different telescope designs are necessary to collect data across the electromagnetic spectrum, from radio waves to gamma rays. For instance, radio telescopes have large dishes or arrays of dishes to collect long wavelengths, while X-ray telescopes use grazing-incidence mirrors to concentrate X-rays on detectors.
