Complimentary colors—why does an object look a particular color to the human eye? specifically describe the copper solution and the colors that would be absorbed by that solution, and the same with the aspirin/iron solution.

When a sample absorbs light from a particular color, we recognize the object as the complementary color, if a sample absorbs red light, our eyes will see the sample appear blue-green.

Explanation:

Copper(II)  ion salts in aqueous ammonia produces a blue solution.  Copper(II) ion salts in aqueous hydrochloric acid produces a green solution.  Based on this evidence, The spectra of the two solutions will have different λmax values. if you add iron III salt to an aspirin you will see a purple color, it means that there is still some salicylic acid present and the sample is impure.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
