**SOLUTION I need help determining the width of a dish**

23/04/2012Â Â· A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a receiver, in much the same way that a parabolic antenna (e.g., satellite dish ) does with radio waves . Parabolic microphones have great sensitivity to sounds in one direction, along the axis of the dish, and can pick up sounds from many meters away. Typical uses of this microphone... The parabolic reflector functions due to the geometric properties of the paraboloidal shape: any incoming ray that is parallel to the axis of the dish will be reflected to a central point, or "focus".

**Experimental base study for finding Maximum Energy**

12/04/2010Â Â· A parabolic television dish antenna is 16 feet across at its opening and 12 feet deep. If the receiver is placed at the focus, how far is it from the vertex? Please do this without using calculus if â€¦... Step 2: Use coordinates to find the focus, vertex, and P, a point on the edge of the dish. If our dish has an 8 ft diameter, this means that it is 4 ft from the axis of symmetry to the edge of the dish.

**Where to find a parabolic dish? Electronics Forum**

The one common feature of all these examples is the parabolic antenna gain, or parabolic dish gain. While the larger antennas have greater levels of parabolic antenna gain, the performance of all these antennas is of prime importance. Factors affecting parabolic reflector antenna gain. There are a number of factors that affect the parabolic antenna gain. These factors include the following... Wel, you're done, you can print that template out any size and go to town, the plywood dish at the beginning was made that way. However if you like, in the next step i'll give you the math. However if you like, in the next step i'll give you the math.

**SOLUTION A satellite dish has a parabolic cross section**

This gives rise to the parabolic dish antennas highly directional radiation pattern. This is why the shape of the dish is parabolic. This is why the shape of the dish is parabolic. Finally, by revolving the parabola about the z-axis, a paraboloid is obtained, as shown below.... Question 744051: A satellite dish has a parabolic cross section and is 6 ft deep. The focus is 4 ft from the vertex. Find the width of the satellite dish at the opening.

## How To Find The Focus Of A Parabolic Dish

### The parabolic reflector functions due to the geometric properties of the paraboloidal shape: any incoming ray that is parallel to the axis of the dish will be reflected to a central point, or "focus".

- If you decide to build a parabolic cooker, you will need to find the focal point of your cooker in order to place your water container where the sunâ€™s rays will be strongest. see it online To see how this point changes with the depth of your dish, you can use the Focus of Parabola demonstra-tion from Humboldt State University, in which you can increase or decrease the curvature of a parabola
- The parabolic reflector functions due to the geometric properties of the paraboloidal shape: any incoming ray that is parallel to the axis of the dish will be reflected to a central point, or "focus".
- A radio telescope has a parabolic dish with a diameter of 100 meters. The collected radio signals are reflected to one collection point, called the "focal" point, being the focus of the parabola. If the focal length is 45 meters, find the depth of the dish, rounded to one decimal place.
- Tto find the position of the origin or vertex of the paraboloid, the midpoint of our chord is at a distance from the axis of the parabola of y = 2.a.tan(theta) or 241 mm. But this point is also at a distance from the lower rim of the dish of d.cos(theta) = d.w / 2d = w / 2 =230 mm. This places the axis (241 - 230) = 11 mm outside the lower rim of the dish, as the solution of the quadratic
