Question

How will the faster vibration of source affect the pitch and frequency?

• A. Both will be lower
• B. Both will be higher
• C. Only pitch will be higher
• D. Only frequency will be higher

Answer 1

The correct option is B

Both will be higher

Frequency is measured as the number of vibration in one second. The unit of frequency measurement is Hertz.

A frequency of 1 Hz means one vibration per second.

The sensation of a frequency is commonly referred to as the pitch of the sound. A high pitch sound corresponds to a high-frequency sound wave and a low pitch sound corresponds to a low-frequency sound wave.

Hence, the faster the vibration of the source, the higher the frequency and pitch.
