The lowest note emitted by a stretched string has a frequency of 40Hz. How many overtones are there between 40Hz and 180Hz?

A.

4

B.

3

C.

2

D.

1

Correct answer is B

f0 = 40H3

1st overtone = 2f0 = 80H3

2nd overtone = 3f0 = 120H3

3rd overtone = 4f0 = 160H3

4th overtone = 5f0 = 200H3

Number of overtones between 40H_{3} and 180H_{3} = 3
