How would the waves change if the students continued moving the ends of the rope up and down the same distance but moved the ends faster?
(1 point)
The wavelength would increase and the amplitude would decrease, but the frequency would be unchanged
The amplitude would increase and the frequency would decrease, but the wavelength would be unchanged
The frequency would increase and the wavelength would decrease, but the amplitude would be unchanged
The wavelength would increase and the frequency would decrease, but the amplitude would be unchanged
1 answer
When the students move the ends of the rope up and down the same distance but do so faster, they are effectively increasing the frequency of the wave. Since the speed of the wave is constant in the medium, an increase in frequency will lead to a decrease in wavelength.
Thus, the correct statement would be: The frequency would increase and the wavelength would decrease, but the amplitude would be unchanged.
