Question

What is the fundamental frequency of a particular medium ?

Answer 1

This is the minimum possible frequency generated by the given medium

Step-by-step explanation:

Let say the medium through which sound is produced is a hollow pipe closed at one end

Now at minimum possible situation the wave that will form in it will be of quarter length so we can say

`L = (\lambda)/(4)`

so we have

`\lambda = 4L`

now we will have

`f = (v)/(\lambda)`

so fundamental frequency of closed pipe will be

`f = (v)/(4L)`

similarly if pipe is closed then in that case the wavelength will be half inside the pipe

`L = (\lambda)/(2)`

now we have

`f = (v)/(2L)`

in this way we can say it is the minimum frequency of sound produced by the source

Answer 2

From my research, the question has the following choices:

a.the lowest frequency at which a standing wave is possible
b. the highest frequency at which s standing wave is possiblec. the only frequency at which a standing wave is possible
d. the only frequency at which standing wave is not possible

From there, the correct answer is A.
