Which physical quantity is measured in hertz?
A. Wavelength
B. Frequency✓ Correct Answer
C. Amplitude
D. Velocity
💡 Solution & Explanation
Frequency is defined as the number of complete oscillations or cycles per second, and its SI unit is the hertz, named in honor of the physicist Heinrich Hertz. Wavelength is measured in meters, amplitude in units of displacement, and velocity in meters per second. A frequency of one hertz corresponds to one cycle per second in periodic phenomena.
