A. B. C. D.A.
The correct answer to this question is A. multipath, reflection, scattering, refraction.
Wireless signals are prone to degradation due to various environmental phenomena. Understanding these phenomena is essential in designing and deploying effective wireless networks.
Multipath occurs when the wireless signal reflects off surfaces and takes multiple paths to the receiver. This can cause the signal to arrive at the receiver at different times and with different phases, resulting in interference and degradation of the signal.
Reflection occurs when a wireless signal bounces off a surface, causing the signal to weaken and lose strength as it travels. This can result in signal attenuation, which can cause considerable degradation of wireless signals.
Scattering is a phenomenon that occurs when wireless signals encounter small objects or rough surfaces, causing the signal to scatter in different directions. This can result in signal attenuation and can cause considerable degradation of wireless signals.
Refraction occurs when a wireless signal passes through a medium with different refractive properties, such as air to water or air to glass. This can cause the signal to bend, resulting in signal attenuation and degradation.
On the other hand, options B, C, and D contain environmental phenomena that are not relevant to wireless signal degradation. Alpha particles, cosmic radiation, gamma rays, and convergence are not factors that can cause considerable degradation to wireless signals. Diversity, absorption, and free path loss are relevant to wireless signal degradation but not as significant as the four phenomena listed in option A.
In conclusion, understanding the impact of multipath, reflection, scattering, and refraction on wireless signals is essential in designing and deploying effective wireless networks.
