What is the primary cause of signal loss in satellite communication?
Free Space Loss is the primary source of signal loss in satellites. As the signal propagates through the atmosphere it disperses. With normal terrestrial antennas, the distance is so short that this is rarely an issue. However, the great distances that satellites must communicate over make this a major problem for global space-based communication.
What did the launch of sputnik in the soviet union and the establishment of the national aeronautics and space administration in the us signal?
the beginning of the space race
Does age affect the way you look at optical illusions?
Yes! Men usually see more of empty space when they look at optical illusions. When women tend to look into the detail.
What is Optical Bay?
An Optical Bay is a designated space within a computer, typically a laptop or desktop, designed to hold optical drives such as CD, DVD, or Blu-ray drives. In many modern devices, this bay may be repurposed for other uses, such as additional storage drives or solid-state drives (SSDs), especially as physical optical media becomes less common. Users can often replace the optical drive with an adapter to install other hardware, enhancing the device's functionality.
Do space colonies exist?
As of August 2014 human colonization of space has yet to have been established. Long term presence in space has been ongoing through orbital space craft and stations however.
What is mean by optical signal?
An optical signal refers to information transmitted using light waves, typically through optical fibers or free space. This form of signaling is commonly used in telecommunications, where data is encoded in light pulses, enabling high-speed and high-capacity data transfer. Optical signals are characterized by their wavelength and frequency, which determine their properties and transmission capabilities.
How long have these microwave photons have been traveling through space?
Microwave photons from the cosmic microwave background radiation have been traveling through space for approximately 13.8 billion years, since the early universe.
What has the author Zabih Ghassemlooy written?
Zabih Ghassemlooy has written: 'Optical wireless communications' -- subject(s): Signals and signaling, Free space optical interconnects, Signal processing, MATLAB, Mathematical models, TECHNOLOGY & ENGINEERING / Lasers & Photonics, Optical communications
Which among the following is considered a line-of-sight communication medium?
A line-of-sight communication medium refers to a transmission method where the sender and receiver must have a clear, unobstructed path between them. Examples include optical fiber, microwave links, and free-space optical communications. These mediums rely on direct visibility for effective signal transmission, making them suitable for applications like satellite communications and certain wireless networks.
Can micro waves travel through a vacuum?
Yes, microwaves can travel through a vacuum because they are a form of electromagnetic radiation, which can propagate through empty space. This is why microwave communication works in space and is used in satellite communications.

Straka has written: 'Optical system contamination' -- subject(s): Space vehicles, Space environment, Contamination, Congresses, Optical equipment, Contamination (Technology) 'Optical system contamination' -- subject(s): Congresses, Space vehicles, Space environment, Optical equipment, Contamination
How many seconds does it take a radio signal to travel one parsec through space?
102,900,000
Is the mountable microwave easy to install in a small kitchen space?
Yes, the mountable microwave is easy to install in a small kitchen space.
What discovery did the optical telescopes make?
the optical telescope has discovered objects on earth and in space
How does a floating microwave work in space?
A floating microwave in space works by using solar panels to generate electricity, which powers the microwave to heat up food or liquids. The lack of gravity in space allows the microwave to float and heat up the contents evenly without the need for a rotating turntable.
What are the best design options for a microwave cabinet in a small kitchen space?
The best design options for a microwave cabinet in a small kitchen space include installing a built-in microwave shelf, utilizing a microwave cart with storage underneath, or incorporating a microwave drawer into the cabinetry. These options help save counter space and keep the microwave easily accessible while maintaining a streamlined look in the kitchen.
What are the types of laser communication?
space .optical
