Answer:
698.46 Hz
Step-by-step explanation:
A note an octave higher than another note is double the amount of frequency.
In this example, the note is 349.23 Hz. Doubled, this is 698.46 Hz. Therefore, the final answer is the first option, 698.46 Hz
The value of the frequency of the musical note one octave above F4 which is about 349.23 Hz is 698.46 Hz.
Frequency of wave is the number of waves, which is passed thorough a particular point at a unit time.
Octave is a interval in music notes, which has the value of sound wave frequency of its higher note twice the frequency of its lower note.
The frequency of the musical note F4 is given in the problem as,
[tex]f_4=349.23 \rm \;Hz[/tex].
The frequency of the note one octave above F4 has to be find out. To The higher note frequency or the frequency of one octave above F4 will be twice the lower note frequency.
Thus, the frequency of one octave above F4, whose value is 349.23 Hz is,
[tex]F_4=2\times349.23\\F_4=698.46\rm\; Hz[/tex]
Hence, the value of the frequency of the note one octave above F4 which is about 349.23 Hz is 698.46 Hz.
