 
 <prompt> Wetin dem fit cast from water or mirrors? Given the previous question, write a context wey contain the answer. E fit be 1 - 20 sentences. Context: <response>: ```The net quality of a ground reflection dey depend on topography of di surface. Wen di surface get small small irregularities pass di wavelength, we dey for specular reflection regime, and di receiver go see both di real antenna and an image of di antenna wey dey under di ground sake of reflection. But if di ground get irregularities wey no be small compared to di wavelength, reflections no go dey coherent but go dey shifted by random phases. With shorter wavelengths (higher frequencies), dis one dey generally happen.```
