Absorption occurs when radio waves are consumed by an object.

• A. Absorbed by an object
• B. Reflected by an object
• C. Refracted by air
• D. Diffracted around obstacles

Answer: (A)

Absorption happens when the energy of the radio wave is taken up by the material it encounters. The wave’s energy goes into the object—often turning into heat or causing molecular or electronic excitations—so less energy remains to be reflected or transmitted. This is why absorption reduces the signal as it passes through or into a material. In contrast, reflection is the wave bouncing off a surface, refraction is the bending of the wave as it changes medium and speed, and diffraction is the wave bending around edges. So the statement aligns with the idea that the wave is consumed by the object.
