If a cross section of a parabolic is 12 inches, the depth is 6 inches, the Mic is placed over the focal point. How far from the vertex should the Mic be placed?
We can use the formula for the focus of a parabola:
f = (1/4)h
where f is the distance from the vertex to the focus, and h is the depth of the parabola.
Plugging in the given values, we have:
f = (1/4)(6) = 1.5 inches
So the focus is 1.5 inches from the vertex.
Since the Mic is placed over the focal point, it should also be 1.5 inches from the vertex.
