Answer:
6.Red
7.600
8.Visible Light Spectrum
9.Visible Light
10.Light has a constant speed of 3 x 10 m/s in any medium
11.both travel at the same speed
12.Infrared waves have a wavelength 1,000x longer than ultraviolet waves (10^-16 vs 10^-13).
13.All electromagnetic waves: are transverse waves; can travel through a vacuum ; travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.
14.The primaries red, green, and blue combine pairwise to produce the additive secondaries cyan, magenta, and yellow. Combining all three primaries (center) produces white.
15.Most colors we see are in reflected light. The different colored objects in the room are reflecting come components of the white light and absorbing the rest. Blue reflects blue wavelengths, absorbs the rest -- a blue shirt demonstrates that white light contains blue light.
