Solution
Correct Answer:
Attenuation
Attenuation is the gradual loss of signal strength (intensity/power) as it travels through a communication medium. It is usually measured in decibels (dB). Causes include absorption by the medium, scattering, and geometric spreading. To overcome attenuation in long-distance systems, 'amplifiers' or 'repeaters' are placed at regular intervals to boost the signal.
This hard difficulty physics question is from the chapter communication systems, covering the topic of attenuation hard. It appeared in the 2025 exam.
