What is reflection?

Explanation:
Reflection is the change in direction of a radio wave when it hits a surface and bounces off. On a smooth surface, the angle at which the wave arrives equals the angle at which it leaves, while on rough surfaces the energy reflects in many directions due to surface irregularities. This is different from diffraction (bending around objects), scattering (redirection in multiple directions), and attenuation (loss of signal strength).
