Using the doppler waves simulation set the unshifted wavelength of the light to 415 nm. set the v/c slider to -0.017 and start the simulation, pausing after waves reach the far side of the screen. with the simulation paused use the distance indicator in the simulation to measure the distance between two successive crests along the dotted line to the right of the moving object. this distance is the apparent wavelength of the light λa.

λa =

using the relationship determine your measured v/c v/c (measured with slider at -0.017) = (record your answer to at least 2 significant figures)

now reset the simulation and set the v/c slider to -0.076 and repeat the steps above

v/c (measured with slider at -0.076) = your answer to at least 2 significant figures)

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Hahahah jsu’s hsjshshsh. shjshshshsh.
