Question

A: The frequency band of VHF is greater than UHF of TV transmission
B: Optical fiber transmission has frequency band of 1 THz to 1000 THz

• A. A is true but B is false
• B. A is false but B is true
• C. A and B are false
• D. A and B are true

Answer 1

Answer: (B)

A is false but B is true

Ultra high frequency (UHF) are radio frequencies in the range between 300 MHz and 3 GHz.
Very high frequency (VHF) are in the range of 30 MHz to 300 MHz.

Optical communication using fibers is performed in the frequency range of 1 THz to 1000 THz.
