Theoretically:
24000miles = 38624.26km = 38624260m
as c (speed of light / speed of electromagnetic radiation / speed of a photon through free space / vacuum = 299792458m/s
and t=d/s
then t = 38624260/299792458
= 0.13s

What uses are there for parabolic mirrors?
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
How many seconds does it take for a microwave to travel from earth to the satellite and back to earth?
Assuming a geosyncronous communications satellite, it is 35,900 km above the surface of the earth. If you are directly beneath it, a microwave will travel at the speed of light (300,000km/s) there and back through this distance. Thus: 2 * 35,900 /300,000 = 0.240 seconds. Note that this is larger if the sender and recipient are located far away, because of the angle.
What is the best way to get tv, phone, & cable OR satellite Thank you!?

Will satellite tv be effected by everything going digital on Feb. 17, 2009?
DTV transition will not affect satellite TV subscribers who receive their local TV stations through their satellite dishes. Satellite TV service is a digital service and all satellite subscribers must have a set-top box connected to their TVs to receive the satellite-delivered programming. you should check with your provider to find out if you receive a local TV station package through your satellite dish just to make sure. Your satellite TV system may be using digital technology as a more efficient way of delivering analog programming to you but if you have an analog television set, then you are probably not getting digital. Bottom line� your satellite tv service might be fine but your tv will not be.
Why are you getting decimal channels through cablevision that look like satellite channels?

How are microwaves transmitted?
Microwaves are electromagnetic radiation. They are electromagnetic waves, and they are transmitted like light or radio waves, both of which are forms of electromagnetic radiation. The radiation leaves the microwave source in waves, and this radiation will travel effortlessly through a vacuum, and with a bit of loss through air.
What is satellite internet?
Satellite internet services are provided through satellite connectivity, it means when you are browsing and streaming you are connected to a satellite network.

How do satellites and TV signals work?
Satellite TV Providers transmits the signals through their satellite dish converting it first from digital signals to analog signals. These signals which were converted will be transmitted to the satellite. The satellite will then transmit the analog signals per request of the satellite dish connected to the receiver of the subscriber. Once signals are received, it will be converted back to digital signals which can be read by the receiver and be displayed to the television.
Do any of the laptop computers come with built in satellite function?

What topology does the cable tv wan use?
Cable TV WANs use a distributed architecture that consists of several star-shaped centralized locations. The focal point in the star is the head-end, which is the central receiving point for signals from various sources, including satellite, other major cable sources, and local television sources. The head-end is a grouping of antennas, cable connections, microwave towers, satellite dishes, and it distills all incoming signal sources and transfers them to remote distribution centers through trunk line.
