Honors Physics - Final Exam Review with Complete Solutions What is the principle of superposition in wave interference? The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves' amplitudes. How does the frequency of a wave relate to its wavelength? The frequency of a wave is inversely related to its wavelength; as the frequency increases, the wavelength decreases, and vice versa. What is the role of an ele...
