Question

What beat frequencies will be present: (a) If the musical notes A and C are played together (frequencies of 220 and 264 Hz)?

a) (44 Hz)
b) (55 Hz)
c) (66 Hz)
d) (77 Hz)

Answer 1

The beat frequency present when musical notes A and C (frequencies of 220 and 264 Hz) are played together is 44 Hz.

Step-by-step explanation:

When two musical notes are played together, beat frequencies can be heard. The beat frequency is the difference between the two frequencies. For example, if notes A (220 Hz) and C (264 Hz) are played together, the beat frequency can be calculated as:

Beat frequency = 264 Hz - 220 Hz = 44 Hz

So, the beat frequency present when musical notes A and C are played together is 44 Hz.
