Find the odd man one. select one:
a. microwaves
b. optical fibre
c. twisted pair wire
d. coaxial cable
Answers
Its a safety glass
Answer:
Microwave is the odd man out.
Step-by-step explanation:
a. Microwaves are electromagnetic radiations with a frequency ranging between 300 MHz to 300 GHz.
b. Optical fibre is a flexible transparent thin fiber made of glass or plastic. It is used to transmit signals through light waves.
c. Twisted pair wire is a cable that comprises of two separate insulated copper wires. twisted together. This is used to transmit electromagnetic waves of frequencies 100Hz to 5Hz.
d. Coaxial cable is a cable consisting of an inner conducting material surrounded by a conducting shield. And both are separated by a dielectric in between them. This is used to transmit the waves of radio frequencies.
In all the above, optical fibre, twisted pair wire and coaxial cable are used to transmit signals of respective frequencies. But microwaves are the waves of certain frequency.
Therefore, among the options the odd man out is microwave.
So, correct answer is option a.
