What else can I help you with?
Which type of waves is not reflected by the ionosphere?
Microwaves are not reflected by the ionosphere because their wavelengths are too short for the ionosphere to effectively reflect them. This is why microwaves are commonly used for satellite communication, as they can pass through the ionosphere to reach satellites in space.
What has bigger wave lengths microwaves or gamma rays?
Gamma rays have shorter wavelengths compared to microwaves. This means that microwaves have longer wavelengths than gamma rays.
Do stars give off microwaves?
Yes, stars emit a range of electromagnetic radiation, including microwaves. This is due to the thermal energy generated in their cores, which causes atoms and molecules in their outer layers to vibrate and release energy in the form of microwaves among other wavelengths.
How do signals travel in space?
Signals travel in space using electromagnetic waves, such as radio waves or light. These waves can travel through vacuum without a medium and carry information encoded in their frequency, amplitude, or phase. Communication between spacecraft and Earth, for example, is achieved by transmitting signals through space using antennas and receivers.
Will a microwave work in space?
No, a microwave oven would not work in space because microwaves rely on the presence of air molecules to transmit heat to the food. In the vacuum of space, there are no air molecules to heat up the food, so the microwave would not function properly.
What gives out microwaves in space?
The background radiation from the big bang
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.
What are the benefits of under cabinet microwaves and how do they compare to traditional countertop microwaves?
Under cabinet microwaves save counter space and provide a sleek look. They are convenient for small kitchens. Traditional countertop microwaves are more portable and easier to install.
What are the advantages of wall mounted microwaves compared to traditional countertop microwaves?
Wall mounted microwaves offer advantages such as saving countertop space, providing a sleek and modern look, and easier access for individuals with mobility issues.
Why can microwaves travel both in an empty space through air an food?
Microwaves are a form of electromagnetic radiation that can travel through empty space and air because they do not require a medium to propagate. When microwaves encounter food, they excite water molecules which creates heat through friction, allowing them to cook food efficiently.
Are built in microwaves and over the range microwaves the same?
Built-in microwaves are designed to be flush-mounted within cabinetry or walls, while over-the-range microwaves are installed above a stove to save counter space and act as a ventilation hood. They serve different purposes and have different installation requirements.
What are the advantages of small microwaves?
Some advantages to owning a small microwave are: They are cheaper than regular microwaves, they take up less space, will require less electricity to function.
Which direction do microwaves travel?
Microwaves travel in a straight line and propagate through space or materials when emitted by a source such as a microwave oven. Their direction can be altered by reflection, refraction, or absorption.
Why do scientists send microwaves into space?
Radio telescopes have beamed messages destined to be picked up by other civilisations. The programme ,SETI is ongoing and the Aricibo Dish in Puerto Rico was used for this purpose. The NASA deep space network used microwaves to communicate with the Apollo astronauts and do today to speak to the international Space Station TV broadcasters send microwaves into space, the signals are received by geostationary satellites to beam the programmes down to Earth to cover a whole country
What are the 4 em waves originated from space?
microwaves, ultraviolet light, infrared, visible light
What is microwaves emitted by?
Microwaves are emitted by microwave ovens, communication devices like cell phones and Wi-Fi routers, radar systems, and some types of astronomical sources in space.
What are the benefits of cabinet microwaves compared to traditional countertop microwaves?
Cabinet microwaves offer a sleek and integrated look in the kitchen, save countertop space, and can be installed at a more convenient height. They also provide better ventilation and can increase the overall value of the kitchen.
