Answer:
1: A mobile phone receives microwave signals from a nearby phone mast (or 'transmitter') and sends microwave signals back. These short bursts of microwave radiation can transmit a lot of information in a very short time. ... Conversations are then encoded as information in digital signals to be carried by these waves.
2: Microwaves are produced inside the oven by an electron tube called a magnetron. The microwaves are reflected within the metal interior of the oven where they are absorbed by food. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food.
Explanation:
Explanation:
Cell phone signals are carried through the air as microwaves. You can see how this works in the Figure below. A cell phone encodes the sounds of the caller’s voice in microwaves by changing the frequency of the waves. This is called frequency modulation. The encoded microwaves are then sent from the phone through the air to a cell tower. From the cell tower, the waves travel to a switching center. From there they go to another cell tower and from the tower to the receiver of the person being called. The receiver changes the encoded microwaves back to sounds.
