Which of the following could be the fundamental freq. for a vibration that has an overtone freq. of 990 Hz?(adsbygoogle = window.adsbygoogle || []).push({});

a. 330

b. 660

c. 148

d. 1980

e. 1990

(All in Hz.)

The formula that I think you have to use is f_n = n*f_1, where f_1 is fud. freq.

Then, I thought

f_2 = 2*f_1, where f_2 is the overtone freq. (is these a correct assumption?)

but 990/2 is 495.

Could someone direct me to the correct path of getting the solution?

I'm confused over the definitions of overtone and fund. freq.

Thanks.
