1) What three objects did we describe in our last in-class exercise? (The subject of each groups questions) 2) If we know that an object normally emits green light, but we now observe that it is emitting microwaves , is it moving toward us or away from us? 3) If we know that an object normally emits violet light, but we now observe that it is emitting blue light, is it moving toward us or away from us? In Class Quiz # 4 Be sure to write your name and the quiz number on the quiz I missed the ordering of quiz 4, so I am giving this one labeled as quiz 4

    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.
