Why infra red communication is called line of sight communication?
Infrared communication is called line-of-sight communication because it requires a direct, unobstructed path between the transmitting and receiving devices. Infrared signals cannot penetrate walls or solid objects, making alignment essential for effective transmission. Any obstacles in the path can disrupt the signal, thus emphasizing the need for a clear line of sight for reliable communication.

What are the uses for infrared technology in communication?
Infrared (IR) can be used by computers and other electronic devices to transfer data to other devices short distances.
Why infra red ray is used in fiber optical communication?
Infrared rays are used in fiber optic communication primarily because they have longer wavelengths, which allows them to travel longer distances with less signal loss and attenuation. Additionally, infrared light can be efficiently generated by lasers and is less affected by scattering and dispersion in the optical fibers. This results in higher bandwidth and improved data transmission rates, making infrared a suitable choice for high-speed communication systems.

How are infrared waves used as communication?
Infrared waves are used for communication by encoding data onto them and transmitting it wirelessly. Devices such as remote controls, IR blasters, and infrared transmitters emit infrared light beams carrying information to be received and interpreted by a compatible device. These waves are typically used for short-range communication within a limited line of sight.
Why is infrared used for communication?
Infrared is used for communication because it is able to transmit data wirelessly over short distances. It is cost-effective, has low power consumption, and offers secure communication as infrared signals do not penetrate through walls easily.
Communication to flight by infrared waves?
Infrared waves can be used to communicate between aircraft and ground stations by transmitting signals encoded with information like altitude, speed, and position. The infrared signals can be received by sensors on the aircraft to establish a two-way communication link between the flight and ground control. This technology provides a secure and reliable method of communication between aircraft and ground stations.
What is scattered infrared?
Scattered infrared refers to infrared radiation that has been deflected or redirected in various directions when it interacts with particles or surfaces. This phenomenon can occur in the atmosphere, on surfaces, or within materials, leading to changes in the distribution of heat and energy.
What type of Electromagnetic radiation used in optical fiber communication?
Optical fiber communication primarily uses infrared light as the type of electromagnetic radiation. This is because infrared light has a longer wavelength that is well-suited for transmitting data over long distances through optical fibers with minimal signal loss.
Why do you think remote controls for TVs vcrs and stereos use infrared light rather than ultraviolet light?
Remote controls use infrared light because it is better at penetrating through obstacles and can be focused into a narrow beam, making it more reliable for communication with devices. Ultraviolet light would not be as effective since it can be absorbed or scattered more easily, leading to a less reliable signal transmission.
What happens to the infrared photons as they interact with the material?
When infrared photons interact with a material, they can be absorbed, reflected, transmitted, or scattered. The specific outcome depends on the properties of the material and the wavelength of the infrared photons.
What radiation reflected light can be scattered?
Visible, ultraviolet, and infrared radiation can all be reflected and scattered by surfaces. When light hits a surface and is scattered, it can disperse in different directions, leading to the perception of reflection.
How effective is an infrared security camera?
Infrared security cameras are very effective. They have the capability to capture pictures in little to no light. They are rated at 82 effective feet.
What blocks infrared radiation from passing through?
Opaque materials, such as metals and certain types of glass, block infrared radiation from passing through. These materials absorb and reflect the infrared radiation, preventing it from transmitting through them.
What are the applications and benefits of using infrared transmissive plastic in electronic devices?
Infrared transmissive plastic is used in electronic devices for applications such as remote controls, sensors, and communication devices. Its benefits include being lightweight, durable, and cost-effective, while also allowing for the transmission of infrared signals without interference.
