Even when Emma turns the machine up to its highest power setting, the rope does not go up high enough to touch the switch. Emma cannot move the switch or the wave generator. What question could Emma investigate to help with her design? A. How can a wave's amplitude be increased without changing its energy? B. What happens to a wave's wavelength when its amplitude decreases? C. What happens to a wave's frequency when its wavelength increases? D. How can a wave's frequency be increased without changing its amplitude? HURRY I AM BEING TIMED HELP
