Physics Question

In the experiment to measure the speed of sound in air, if a graph is drawn, and it doesnt go through to the origin, instead goes beneath the origin, if you were asked to find the approximate diameter of the tube would it be -0.3(the place the line intersects the y-axis) ?

as far as i know its is where it hits the y-axis, your right 0.3

Yeah , where it intersects the y axis will give you the value.
