Light at 427 is Violet in color and light at 603 nm is orange in color. Svhich of the following conclusions about solution color, light color, and absorbaDce is best. supported by the results of Experiments l and 2 ? Blue solutions tend to absorb violet ]ight: tions tend to absorb violet light more Strongly than orange light. more strongly than Orange light, and yellow solu- tions tend to absorb violet light less strongly tha orange light.

In each trial. the students mounted 2 UDcharged con- ducting spheres D cm apart on the stands..Then they placed a negative charge on each gphere. The electric force between the spheres caused Stand 2's sphere to move away from Stand I's spbere. thereby twisting the vcrtical wire clockwisc (sce Figure 2).
