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.
What such as microwaves can travel through a vacuum?
Electromagnetic waves, such as microwaves, can travel through a vacuum because they do not require a medium for propagation. This is due to their unique properties of electric and magnetic fields oscillating perpendicular to each other and the direction of travel. This allows them to pass through empty space with no need for a material medium.
Can micro waves travel through a vacuum?
Yes, microwaves can travel through a vacuum because they are a form of electromagnetic radiation, which can propagate through empty space. This is why microwave communication works in space and is used in satellite communications.
What wave does not require a medium but can travel through empty space?
Electromagnetic waves do not require a medium to travel and can propagate through empty space. These waves include visible light, radio waves, microwaves, X-rays, and gamma rays. They are caused by oscillating electric and magnetic fields.
What type of energy can travel trough empty space and travels in waves?
Electromagnetic energy can travel through empty space and travels in waves. This includes visible light, radio waves, microwaves, X-rays, and gamma rays.

Which type of wave can travel through empty space by electromagnetic waves?
Electromagnetic waves are a type of wave that can travel through empty space. They do not require a medium to propagate because they consist of oscillating electric and magnetic fields that can travel through a vacuum. Examples of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Which kind of energy travels as waves and moves through empty space?
Electromagnetic waves, which includes light. Also, gravitational waves.
What can travel either travel through matter or through empty spaces.?
volume
Which do not travel through empty space?
Sound waves do not travel through empty space because they require a medium, such as air, water, or a solid, to propagate. Similarly, mechanical waves like seismic waves also need a medium to travel and cannot propagate through empty space.
Can travel though empty space?
Yes, you can travel through empty space. The Sun, Earth, moon, satellites, space ships, atoms, and subatomic particles all travel through empty space. Greater than 99.999% of matter is empty space.
Why can microwaves travel through both empty space and through air and food?
That shouldn't be too surprising when you recall that in addition to empty space, radio can travel through walls, heat can travel through air, light can travel through glass and water, and x-rays can travel through steel and bones. All electromagnetic radiation is absorbed to some extent by passing through a material medium. The amount of absorption depends on the material, and also on the wavelength of the radiation. In the case of microwave radiation at 2.5 GHz, we are very happy that some foods absorb it quite well, otherwise we couldn't cook a turkey in 3 minutes in the microwave oven. Microwaves travel through empty space unimpeded just as light. If truly empty space they should theoretically travel forever. Air is not truly empty and microwaves can interact with the air molecules, losing energy as it does so, but will still travel a great distance before being totally attenuated. However, material objects, such as food, have dielectric properties that affect the way microwaves interact with them and will attenuate them in shorter distances. While air has a relative dielectric constant of 1.0, water is 78 and beef 80 at room temperature. The microwave energy will be strongly attenuated by these materials and will travel a relatively short distance. In water, for example, 63% of the microwave energy is attenuated in 1.2 cm (< 1/2") and so will effectively about 95% absorbed in 6 cm. (the number is accurate because it doesn't take into account the change in the dielectric constant with temperature, but is good enough to demonstrate the effect.)
