Question

Which best describes pitch?

Answer 1

Answer:

B) the number of cycles per second perceived by the human ear

Explanation:

The best expression that describes pitch is that it is the number of cycles per second perceived by the human ear.

For a wave train, the number of cycles per second is frequency. Whereas the period is the amount of time taken for a longitudinal wave to produce one cycle.

The distance between two corresponding parts of a transverse wave is its wavelength.

• A high pitch will correspond to a high frequency of waves perceived.
• A low pitch corresponds to a low frequency of waves.
