Which quantity of the wave will increase?

A. Speed
B. Frequency
C. Amplitude
D. Wavelength

C. Amplitude

The quantity of the wave that will increase depends on the specific scenario and context. However, generally speaking:

A. If the speed of the wave increases, it means that it is traveling faster through the medium.

B. If the frequency of the wave increases, it means that the number of wave cycles occurring per unit of time increases.

C. If the amplitude of the wave increases, it means that the maximum displacement or height of the wave from its equilibrium position increases.

D. If the wavelength of the wave increases, it means that the distance between two corresponding points on the wave, such as two peaks or two troughs, increases.

Therefore, to determine which quantity of the wave will increase, you need to specify the specific scenario or context.
