Question

Of the four waves whose frequencies are listed below, which has the shortest period?

A) 12 kHz (kilohertz).
B) 6,000 Hz (or 6 kHz).
C) 205 Hz.
D) 1 kHz (kilohertz).

Answer 1

The wave with the shortest period is the one with the highest frequency, which is 12 kHz.

Step-by-step explanation:

In physics, the period of a wave is the time it takes for one complete cycle or wave to pass a specific point. The period is inversely related to the frequency of the wave, meaning that a higher frequency corresponds to a shorter period. So, of the four waves listed, the one with the highest frequency will have the shortest period.

Looking at the frequencies given:

• 12 kHz = 12,000 Hz
• 6,000 Hz
• 205 Hz
• 1 kHz = 1,000 Hz

Therefore, the wave with the shortest period is the one with the highest frequency, which is 12 kHz.
