Question

What error did the students make in labeling the distance from the rim of the cup to the center as the wavelength of the sound wave?

a) They mistook amplitude for wavelength.
b) They confused frequency with wavelength.
c) They misidentified the diameter as the wavelength.
d) They misinterpreted the ripples as sound waves.

Answer 1

The students made the error of confusing frequency with wavelength when labeling the distance from the rim of the cup to the center as the wavelength of the sound wave.

Step-by-step explanation:

The students made the error of confusing frequency with wavelength when labeling the distance from the rim of the cup to the center as the wavelength of the sound wave. Wavelength refers to the distance between two wave crests or two wave troughs, while frequency is the number of wave crests that pass a point per second. By mistaking frequency for wavelength, the students misunderstood the characteristic of the sound wave.
