To calculate : The depth of antenna using the equation for the cross section of the antenna with its vertex at origin and its focus
The depth of antenna is about
Given information :
A parabolic microwave antenna is
Calculation :
Given depth of the parabolic microwave antenna is
Write an equation for the cross section. Since the focus is to the right of the vertex
The standard form of the equation of a parabola with vertical axis of symmetry is
Substitute
The equation for the cross section is
Find the depth of the antenna.
The depth is the
Substitute
Take the square root on both the sides.
Therefore, the depth of antenna is about
