ANSWER:
The device that I found in my home that can use electromagnetic waves was a cellular phone. Cellular phones utilize electromagnetic waves through Radiofrequency (RF) radiation, which includes radio waves and microwaves. These two types of EM Waves send signals to and receive them from nearby cell towers or base stations using RF waves. The network of fixed antennas carries signals to deliver information between the sender and receiver. Thus, in the current society, the further utilization of these waves on cellular phones is used as a means of communication throughout the world.
