The frequency of the musical note G4 is about 392.00 Hz.

What is the frequency of the note one octave below G4?

196.00 Hz

492.00 Hz

588.00 Hz

784.00 Hz

196.00 Hz

The correct option is 1.

Step-by-step explanation:

It is given that the frequency of the musical note G4 is about 392.00 Hz.

We have to find the frequency of the note one octave below G4. It means the required frequency must be less than the frequency of G4, i. e. 392.00 Hz.

In option 1,

196.00 Hz < 392.00 Hz

Therefore option 1 is correct.

In option 2,

492.00 Hz > 392.00 Hz

Therefore option 2 is incorrect.

In option 3,

588.00 Hz > 392.00 Hz

Therefore option 3 is incorrect.

In option 4,

784.00 Hz > 392.00 Hz

Therefore option 4 is incorrect.
