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 2
X-ray telescopes are located in orbit around the Earth because:
A) X-ray telescopes on Earth would have to be too big.
B) X-ray telescopes are cheap and easy to launch into space.
C) there are too many X-ray telescopes on Earth, so now they are put in space.
D) X-rays don't reach the surface of Earth.
E) the X-rays that come out of the telescopes are dangerous to humans.
