Imagine a group of people standing in a circle. There are two ways that they can create a “wave”. One way is by placing the palms of their hands together. One person begins by pushing on the adjacent person's palm who, in turn, pushes on the next person's palm, etc. Another way is by adjacent people holding hands. One person lifts the other person's hand and then that person lifts the next
person's hand, etc. Which types of waves are represented by each case?
1.Both cases represent longitudinal waves.
2.The first case represents a transverse wave and the second case represents a longitudinal wave.
3.Both cases represent transverse waves.
4.The first case represents a longitudinal wave and the second case represents a transverse wave.

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.
