Final Answer:
The correct representation for the frequency 161.775 MHz is "One-six-one point seven seven five megahertz. C. One-six-one point seven seven five megahertz.
Step-by-step explanation:
In this frequency, MHz stands for megahertz, which indicates a unit of measurement for frequency. The frequency 161.775 MHz should be read as "one-six-one point seven seven five megahertz." The number before the decimal point represents the hundreds, tens, and ones place, while the numbers after the decimal point indicate tenths, hundredths, and thousandths of the frequency.(C)
Frequency measurements involve precise decimal readings where each digit represents a specific magnitude of the frequency. In this case, 161 denotes the hundreds, tens, and ones place, while .775 specifies seven tenths, seven hundredths, and five thousandths of a megahertz. Properly reading out each digit is crucial in relaying accurate frequency information for various technological applications, such as radio communications, where precise frequency allocation is vital for signal transmission and reception.
When expressing frequencies, it's important to articulate each digit distinctly, especially when dealing with intricate technological specifications. The correct verbal representation aids in clear communication and ensures accurate interpretation, preventing errors in the transmission and utilization of frequency-based information across different technological systems and devices.
