Propagation refers to the process of reproducing or spreading plants, animals, or other organisms. In gardening, for example, it involves techniques like planting seeds, taking cuttings, or dividing existing plants to create new ones. This helps to increase the number of plants and can enhance biodiversity. In technology, propagation can describe how signals or waves travel through different mediums. For instance, in telecommunications, the propagation of radio waves allows for wireless communication. Understanding propagation is essential for improving signal strength and coverage in devices like smartphones and Wi-Fi routers.
