How can you express sound wave frequency?

• A. In Decibels (dB)
• B. In Hertz (Hz)
• C. In Amperes (A)
• D. In Ohms (Ω)

Answer: (B)

Sound wave frequency is expressed in Hertz (Hz), which measures the number of cycles of a sound wave that occur in one second. This unit indicates how often the wave oscillates, allowing us to understand the pitch of the sound produced; higher frequencies correspond to higher pitches, while lower frequencies relate to lower pitches. The other choices relate to different properties of sound and electrical systems. Decibels (dB) are a unit for measuring sound intensity or power, not frequency. Amperes (A) measure electric current, and Ohms (Ω) represent electrical resistance. Each of these has its distinct application in the field of audio and sound engineering, but they do not quantify sound wave frequency like Hertz does.
