Answer 1
amplitudes
CORRECT
both waves have different heights from the center of the graph which means they have different amplitudes. return to top
Answer 2
frequncies
INCORRECT
both waves complete the same number of cycles in the same period so they have the same frequncies and answer B is incorrect. return to top
Answer 3
speeds
INCORRECT
both waves travel the same distance in the same period of time so there speeds are the same and answer C is incorrect. return to top
Answer 4
wavelenghts
INCORRECT
each wave completes the same number of cycles in the same period of time so they don't have different wavelenghts and answerD is incorrect return to top
