What is amplitude and frequency of sound?
What is amplitude and frequency of sound? [BL] For sound, a higher frequency corresponds to a higher pitch while a lower frequency corresponds to a lower pitch. Amplitude corresponds to the loudness of the sound. [BL][OL] Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. How is frequency related to amplitude? The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the...
