**The Intensity of a Harmonic Wave**
The intensity of a harmonic wave refers to the amount of energy that the wave carries per unit of time through a unit area perpendicular to the direction of wave propagation. It is a measure of the power or strength of the wave.
**Dependence on Frequency**
The frequency of a wave refers to the number of complete oscillations or cycles that the wave undergoes per unit of time. It is measured in hertz (Hz). The frequency of a harmonic wave determines the pitch or tone of the wave.
The intensity of a harmonic wave depends on its frequency. This is because the energy carried by the wave is directly proportional to the frequency of the wave. When the frequency of a wave increases, the number of oscillations per unit of time also increases, resulting in more energy being carried by the wave. Therefore, the intensity of a harmonic wave increases with an increase in frequency.
**Dependence on Amplitude**
The amplitude of a wave refers to the maximum displacement of particles in the medium from their equilibrium position. It is a measure of the wave's maximum magnitude or strength. The amplitude of a harmonic wave determines the loudness or volume of the wave.
The intensity of a harmonic wave also depends on its amplitude. This is because the energy carried by the wave is directly proportional to the square of its amplitude. When the amplitude of a wave increases, the maximum displacement of particles from their equilibrium position also increases, resulting in more energy being carried by the wave. Therefore, the intensity of a harmonic wave increases with an increase in amplitude.
**Combined Dependence on Frequency and Amplitude**
Since the intensity of a harmonic wave depends on both its frequency and amplitude, the correct answer is option C. Both factors contribute to the overall energy carried by the wave and, consequently, determine its intensity. By adjusting the frequency and amplitude of a harmonic wave, it is possible to manipulate its intensity and, therefore, its characteristics such as pitch, volume, or brightness.
In summary, the intensity of a harmonic wave depends on both its frequency and amplitude. The frequency determines the energy carried per unit of time, while the amplitude determines the maximum magnitude of the wave. By considering both factors, we can understand how the energy of the wave is distributed and how it affects our perception of the wave's properties.
