Q: Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies.  Eric is looking at the longest electromagnetic wave he has seen today. This wave has the highest or lowest frequency of the day?
A: lowest


Q: Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures.  Would a star that is significantly hotter than the sun, which is outputting blue light which is higher in frequency that the yellow light of the Sun, be hotter or colder??
A: hotter


Q: The closer objects are, the stronger the gravitational pull between them.  Does a ball in space have more or less gravity on it than on earth more or less?
A: less


Q: Its harder to overcome friction between heavier objects and the floor than it is between lighter objects and the floor.  Fred was moving a desk across the room. He then pushed a chair and it was much easier. This is because the lighter chair had less or more friction with the floor?
A: less
