When frequencies are high enough (we're talking tens of gigahertz), the waves can be stopped by objects like leaves or raindrops, causing the phenomenon known as "rain fade".
Wakati frekvenser ni juu ya kutosha (tunazungumzia makumi ya gigahertz), mawimbi zinaweza kuzuiliwa na vitu kama majani au Raindrops, kusababisha athari ya jambo linalojulikana kama "fade mvua".
