In the following sub-questions, use your book and notes to generate an argument for each model of light. Remember, on the first day of class we discussed that argumentation requires: ● a claim (which I've given), • evidence (which you should look up in the form of data or scientific principles) and reasoning that connects the evidence to the claim (which you should generate from your understanding so far).
Which answer is the most correct between the two?
