Chapter 20: Problem 2700

In which frequency range, space waves are normally propagated ? (A) HF (B) VHF (C) UHF (D) SHF

Short Answer

Expert verified
Space waves are typically propagated in the VHF and UHF frequency ranges, so the correct options are (B) VHF and (C) UHF.

Step by step solution

01

Understand Space Waves

Space waves are a type of electromagnetic waves that travel through the atmosphere, directly from the transmitter to the receiver. They don't rely on reflection from the Earth's surface or the ionosphere and are mainly used for line-of-sight communication between antennas.
02

Identify the Frequency Range for Space Waves

Space waves typically propagate in the VHF (Very High Frequency) and UHF (Ultra High Frequency) frequency ranges. In these ranges, the antennas are smaller and more affordable, the signals are less affected by the Earth's surface and buildings, and the waves can penetrate through walls and other obstacles more effectively.
03

Choose the Correct Option

As space waves are typically propagated in the VHF and UHF frequency ranges, the correct option is (B) VHF and (C) UHF.
