What type of rays do cellphones and ovens use?
Cellphones use radio waves for communication, while ovens use electromagnetic radiation (infrared radiation or microwaves) to heat or cook food.
What type of rays do microwaves use for cooking food?
Microwaves use electromagnetic radiation, specifically microwaves, to cook food.
Why is mercury used in microwaves?
Mercury is not used in microwaves. Microwaves use magnetrons to generate microwave radiation, which heats food by causing water molecules to vibrate. Mercury is a toxic element and is not safe for use in consumer products like microwaves.
How do microwaves use microwaves to heat food?
Microwaves use electromagnetic radiation at a specific frequency to agitate water molecules in food, causing them to vibrate and generate heat through friction. This heats up the food quickly and evenly.
What form of energy do you think microwaves ovens use explain your reasoning?
Microwave ovens use electromagnetic energy in the form of microwaves to heat food. The microwaves cause water molecules in the food to vibrate, generating heat that cooks the food.
