Olivia properly answered most of the questions on the review sheet. I discussed with her any questions she was unsure of, which immediately elicited the correct response.
Using pictorial representations of a wave, the relationship between velocity, frequency, and the wave length was determined and formulated as velocity = frequency x wavelength. Olivia then rearranged the formula to solve for any one unknown given the other two.The results of an experiment was written on the board which calculated the velocity of different waves given their wavelengths and frequencies. It was determined that the velocities were all the same and that the wavelength and frequency vary inversely to produce the same velocity. This is the reason why high and low frequency musical instruments can be heard all at the same time during a concert.
