Where were microwaves first used?
Microwaves were first used during World War II for radar equipment. After the war, Percy Spencer, an engineer at Raytheon, noticed that a candy bar in his pocket had melted near a magnetron tube, leading to the development of the microwave oven for cooking.
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.
What two uses for microwaves?
Microwaves are commonly used for cooking food quickly and efficiently. They are also used in communication technology, such as in radar systems and satellite transmissions.
What do they use microwaves for?
Microwaves are commonly used for cooking and heating food quickly. They work by exciting water molecules in food, causing friction and generating heat. Microwaves are also used in communication technology, such as for satellite communication and radar systems.
Are microwaves matter?
Microwaves are a form of electromagnetic radiation, not matter. They are characterized by their wavelength in the electromagnetic spectrum and are commonly used in cooking and communication technologies.
How were microwaves used?
microwaves are used to warm or cook something. the electricity powers the microwave so it will create heat. First use was by the military -- RADAR
Which of the following is true of microwaves?
microwaves are used in radar

How are microwaves helpful in your lives?
Microwaves can be used to send signals or to cook food.
Why is mercury used in microwaves?

Microwaves are used for?
To warm-up foods !
Can microwaves carry information?
yes it can because microwaves are used for many thinks(ex) tv telephone and computer
Why were the first microwave ovens referred to as radar ranges?
because microwaves both and radar systems both use microwaves

Can water absorb microwaves?
Yes, water can absorb microwaves because its molecules have a positive and negative charge that can align with the alternating electric field of the microwaves, causing them to oscillate and generate heat. This is why microwaves are commonly used to heat food that contains water.
