### Step-by-Step Solution: 1. **Understanding Ground Wave Transmission**: Ground wave transmission refers to the propagation of radio signals along the surface of the Earth. This method is particularly useful for communication over short to medium distances. 2. **Energy Absorption by the Earth**: In ground wave transmission, the energy of the radio signal is partially absorbed by the Earth. This absorption is a significant factor that affects the efficiency of the transmission. ...
