Pitch is _ proportional to frequency.
Correct answer: A. Directly
- A. Directly
- B. Inversely
- C. Exponentially
- D. No effect
Explanation
The quality of a sound governed by the rate of vibrations producing it is called pitch. While frequency is defined as the number of vibrations produced per second. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. Hence, pitch is proportional to frequency.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
