Three sound waves travel through air at the same speed and have equal amplitudes.
• Wave X: wavelength = 2.0 m
• Wave Y: wavelength = 1.5 m
• Wave Z: wavelength = 1.0 m
Which of the following correctly ranks the waves from greatest to least in both perceived pitch and energy transported?
(a) Z>Y>X for pitch; all three have equal energy
(b) Z>Y>X for both pitch and energy
(c) X>Y>Z for pitch; Z>Y>X for energy
(d) Z>Y>X for pitch; X>Y>Z for energy
