Marshal McLuhan I believe.
travels through a uniform medium
it travel in a staight line
Light will propage in "a straight line" when passing through a single medium. The "straight line" however bends depending on the gravitation curvature of the volume being passed through.
Medium A is the more optically dense medium. As when the light enters B its speed increases taking it toward the normal.
TV transmission from one antenna to other antenna is a clear example of line of sight communication.
Line of sight communication is in the VHF and higher frequencies of the RF spectrum where the wavelength is to short to pass over structures and hills, the transmitter and receiver antennas must be in line of site
Line of Sight communication, in the technological sense, is a type of data transfer that requires "visual contact" with the two devices/antennas. Common line of sight communication are Infared (such as a typical TV remote), or any visible spectrum, to very high-frequency bandwidth (above 5GHz). Where the signal cannot travel over/bend around objects (unlike radio frequency, that can "warp" around objects").
Microwave wireless communication is a Line of Sight communication. Microwave communication occurs at 3Ghz to 30Ghz. Line of Sight means there should not be any restriction between the Antenna i.e. two antenna can see to each other. it is an easy way for communication. In telecom field,Microwave communication is used to Link BSC to BSC,BSC to MSC and MSC to MSC and so on.
ex of line of sight is infrared that cant work properly if its not in a line n ex of non line of sight is bluethut that can work correctly even if they arnt in a same line.. and that's it.. mata nor na razi.....
commonest medium of communication
Yes, Infrared is definitely a line of sight communications device, as infrared wavelengths cannot bend around any type of objects, the devices have to be within visual contact to communicate.
what is the line of sight equation
Infrared communication is impaired by loss of a direct line of sight. This is caused by physical obstructions between the emitter and receiver.
a face-to-face communication
