The maximum height that the particles of a medium move from the rest position is the
a. amplitude of the wave.
b. wavelength of the wave.
c. frequency of the wave.
d. speed of the wave.
To find the maximum height that the particles of a medium move from the rest position, you need to understand the key properties of a wave.
The amplitude of a wave refers to the maximum displacement of the particles from their equilibrium position, or the maximum height that the particles move from the rest position. Therefore, the correct answer is option a. Amplitude of the wave.
