Question

In this scale, the frequency of each C-note in vibrations per second is measured in Hz. It can be expressed as a power of 2, as shown. What is the frequency of the note C7 in exponential form and in logarithmic form?

C4: 256 Hz
C5: 512 Hz
C6: 1024 Hz

Answer 1

log form:
\[\log_{2}2048=11\]
exponential form:
2^11=2048

Answer 2

thank you :)


If the frequency of a note C is 32 vibrations per second, how many octaves higher or lower than middle C is this note?
