Question

directions: sort the following as a characteristic of wavelength, frequency or amplitude. associated with the energy of a mechanical wave. options: wavelength, frequency, amplitude

Explanation:

To determine the characteristic associated with the energy of a mechanical wave, we recall the properties of waves:

• Wavelength is the distance between consecutive crests/troughs, related to spatial period, not directly energy.
• Frequency is the number of cycles per unit time, related to energy in electromagnetic waves (via \( E = hf \)) but for mechanical waves, energy is more directly tied to amplitude.
• Amplitude is the maximum displacement of a point on the wave from its rest position. For mechanical waves (like sound, as depicted by the speaker), the energy is proportional to the square of the amplitude (\( E \propto A^2 \)). So the characteristic associated with the energy of a mechanical wave is Amplitude.

Answer:

Amplitude
