Chapter 20: Problem 2695

Space waves are generally propagated in (A) UHF (B) VHF (C) HF (D) None of there

Short Answer

Expert verified
Space waves are generally propagated in the highest frequency range among the given options, which is (A) UHF (Ultra High Frequency: 300 MHz to 3 GHz). This is due to their ability to penetrate obstacles and travel through the atmosphere more effectively at higher frequencies.

Step by step solution

01

Understanding Space Waves

Space waves are electromagnetic waves that travel directly from the transmitter to the receiver without reflecting off the Earth's surface or the ionosphere. They are used primarily for communication over short to medium distances.
02

Understanding Frequency Ranges

The given frequency ranges are: - UHF (Ultra High Frequency): 300 MHz to 3 GHz - VHF (Very High Frequency): 30 MHz to 300 MHz - HF (High Frequency): 3 MHz to 30 MHz
03

Comparing Frequency Ranges and Space Wave Propagation

Space waves travel in a straight line, and as such, their effectiveness is determined by factors such as their frequency, which affects their ability to penetrate obstacles and the atmosphere. The higher the frequency of a wave, the shorter its wavelength, making it more effective at penetrating obstacles and traveling through the atmosphere. Therefore, space waves are generally propagated in higher frequency ranges.
04

Comparing Frequency Ranges

Now that we know space waves are generally propagated in higher frequency ranges, we can compare the options and pick the correct one: - UHF (Ultra High Frequency): 300 MHz to 3 GHz (the highest frequency range among the given options) - VHF (Very High Frequency): 30 MHz to 300 MHz - HF (High Frequency): 3 MHz to 30 MHz
05

Selecting the Correct Option

Based on the analysis above, space waves are generally propagated in the highest frequency range among the given options, which is UHF (Ultra High Frequency). So the correct answer is: (A) UHF
