Lori Baker Page 1 Chapter 5 Review Questions 1. Why would you not plot sound waves in the electromagnetic spectrum? Because sound waves are acoustic and not electromagnetic. Sound waves require a medium. electromagnetic waves propagate through a vacuum by means of the oscillating electric and magnetic fields. That's why in space no one can hear you scream. 2. If you had limited funds to build a large telescope, which type would you choose, a refractor, or a reflector? Why? Reflector because they are much less expensive. 3. Why do nocturnal animals usually have large pupils in their eyes? How is that related to the way astronomical telescopes work? Pupils get large so more light will enter to allow the animals to see at night. Telescopes have large lenses to allow more light in.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
