The core refractive index should be lesser than the cladding refractive index for a coaxial cable. State True/False

The core refractive index should be lesser than the cladding refractive index for a coaxial cable. State True/False Correct Answer False

The light should pass through the core region only, for effective transmission. When light passes through cladding, losses will occur, as cladding is meant for protection. Thus core refractive index must be greater than the cladding refractive index.

You are setting up a network in a school. You need to network 5 computers for the file and printer sharing. You want to use some donated cable and Ethernet adapters. You identify the donated adapters as ARCnet coaxial network adapters and 10Base2 Ethernet network adapters. You install an Ethernet adapter in each of the 5 computers and connect the donated cable. The computers are NOT able to maintain reliable communication. You suspect that you are NOT using the correct type of coaxial cable. Which type of coaxial cable should you be using?
Choose the correct relation for a combination of two prisms to be achromatic. (Where for the first prism: μv = refractive index of the medium in violet light, μr = refractive index of the medium in red light A = angle of the prism; For the second prism: μ′v = refractive index of the medium in violet light, μ′r = refractive index of the medium in red light, A’ = angle of prism.)
Losses caused by factors such as core-cladding diameter, numerical aperture, relative refractive index differences, different refractive index profiles, fiber faults are known as ____________
S1: Instantly the full load yanked Gordy towards the side of the bridge.
P: But the pull of the cable was too much.
Q: He could hardly feel the cable, slipping through his fingers, ripping off his gloves, and streaking over the railing like an escaping snake.
R: It smashed his hands hard against the top of the railing, causing a split - second feeling of fierce pain followed by numbness.
S: He held on to the cable; it had been hard work lifting it, and he did not want to have to start over again.
S6: Feeling a sharp burning sensation where the cable was speeding between his things, Gordy rose on tiptoe and as he did, the slithering coil of cable tightened around his left foot and yanked him over the railing.
