What is microwave and examples?
Microwave is defined as the part of the electromagnetic spectrum with large infrared waves and short radio waves, an oven that cooks food very quickly or made to cook in one of these ovens. An example of microwave is frozen foods that are made to cook very quickly; microwave food.
What are 5 uses of microwaves?
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial …
What is microwave in simple words?
A microwave is a small oven that cooks or heats food very quickly. Its radiation, or waves, penetrate the food and heat up any moisture inside it. These waves are themselves called microwaves because they’re short (and micro- means “small”), similar to radio waves.
How are microwaves helpful?
Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke. Shorter microwaves are used in remote sensing. This microwave tower can transmit information like telephone calls and computer data from one city to another.
What are the two uses of microwave?
They are used for point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial heating, collision avoidance systems, garage …
What is microwave Class 12?
1. The microwaves are the electromagnetic waves having frequencies in the range 300 MHz to 300GHz. Microwaves heat an object on which they are incident. This property is used in electrical appliances such as a microwave oven.
How are microwaves used in daily life?
Microwaves cause water and fat molecules to vibrate, which makes the substances hot. So we can use microwaves to cook many types of food. Mobile phones use microwaves, as they can be generated by a small antenna, which means that the phone doesn’t need to be very big. Wifi also uses microwaves.
What is microwave in science?
Microwaves are a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and gamma-rays. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum EM spectrum).
How does a microwave works?
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.

How are microwaves used for communication?
Microwaves are used to send signals to and from satellites. The satellites can relay signals around the Earth. Mobile phones use microwave signals. The signals from the transmitting phones reflect off metal surfaces and walls to communicate with the nearest transmitter mast.
