Question

1. What is microwave?
2. What is radiowave?
3. What is satellite?
4. What Wi-Fi and Bluetooth?
5. What is laser communication?​

Answer 1

Answer:

1. Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF bands.

2. an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication.

3. the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

4.Both Bluetooth and Wi-Fi are used for providing wireless communication through radio signals. The most distinction between Bluetooth and Wifi is that, Bluetooth is actually accustomed connect short-range devices for sharing information whereas Wifi is used for providing high-speed web access or internet.

5. Laser communications systems are wireless connections through the atmosphere. They work similarly to fiber optic links, except the beam is transmitted through free space. ... The carrier used for the transmission signal is typically generated by a laser diode.

Answer 2

Answer:

Q1 answers-Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF bands.

Q2 answers-Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz to as low as 30 hertz. At 300 GHz, the corresponding wavelength is 1 mm; at 30 Hz the corresponding wavelength is 10,000 km.

Q3 answers-In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon. On 4 October 1957, the Soviet Union launched the world's first artificial satellite, Sputnik 1.

Q4- Bluetooth allows for short-range data transfer between devices. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Wi-Fi, on the other hand, allows devices to connect to the Internet.

Q5Laser communication in space is the use of free-space optical communication in outer space. Communication may be fully in space or in a ground-to-satellite or satellite-to-ground application.
