Question
Which of the following has the lowest frequency and lowest amplitude?
Hint:
Frequency and amplitude are characteristics of a sound wave
The correct answer is:
- Amplitude is the maximum displacement of the particles of a sound wave.
- The total number of waves produced in one second is called the frequency of the wave.
- Therefore, the wave which has the lowest frequency and lowest amplitude is a.
- So, the correct option is a.
