Question

All satellites use parabolic reflectors only. This statement is: Correct incorrect. [2] The principal axis is drawn: outward from the center of the surface, so that surface is symmetrical about the axis, so that all reflection occur along the entire axis, outward from end of the surface [3] The parabolic reflector focuses on: a parabolic shape, a spherical shape, a single point, a small line. [4] The spherical reflector focuses on: a parabolic shape, a spherical shape, a single point, a small line. [5] The transmitter must be placed: anywhere along principal axis, at center of dish, at edge of dish, at the focus

Explanation / Answer

1.It is correct, all satellites use parabolic reflectors.

2.The principle axis is drawn so that surface is symmetrical about that axis.

3. The parabolic reflectors focus on a single point.

4. The spherical reflectors focus on a single point. Note:- but there us some spherical aberration i.e. its not exactly at a point, but close enough.

5.The transmitter must be placed at the focus.
