Electromagnetic waves are created by the movement of charged particles. These waves consist of oscillating electric and magnetic fields that propagate through space at the speed of light.
Lead is a good shield against electromagnetic waves due to its high density and atomic structure, which can absorb and block the waves. However, lead can also partially resist electromagnetic waves depending on their frequency and intensity.
Electromagnetic waves do not require a medium for energy transfer. These waves can travel through a vacuum because they are made up of changing electric and magnetic fields. Examples of electromagnetic waves include light, radio waves, and X-rays.
No, electromagnetic waves are not mechanical waves. Mechanical waves require a medium through which to travel, such as air or water, while electromagnetic waves can travel through a vacuum. electromagnetic waves are created by oscillating electric and magnetic fields and can travel through empty space.
Electromagnetic waves are called EM waves because they are composed of oscillating electric and magnetic fields. These fields propagate through space, carrying energy with them. The combination of electric and magnetic fields gives rise to the term "electromagnetic."
Electro magnetic waves can pass through medium of free space ie vacuum but mechanical waves cannot do so. Mechanical waves such as sound definitely needs a material medium air, water etc. But light being electro magnetic could pass through even vacuum. Actually in between the sun and earth there is vacuum. Yet we receive light right from Sun towards earth.
The uses of electro magnetic waves in medicine?
They are electromagnetic.
Self propagating electro-magnetic waves. Otherwise known as light waves.
Communications Satellites ************************ Electro-magnetic waves. Carrier waves.
Sure, it just sucks when you drop the microwave in the bathtub.....
electro magnetic waves that turn into sound energy and changes info
Heat is transferred by electro magnetic waves, for the case with fire it's infra red waves.
Electric waves produced due to lightning and radio waves (Long waves) are invisible electro magnetic radiations.
Radio waves as low as 10kHz are used for communication with submarines.
No. At least not in the lifetime of any individual currently extant, for sure.
EM is just shorthand. E for electro, M for magnetic. Electromagnetic. Pretty cool huh?
emi in electronics is electro-magnetic interference. I do not know of any advantage as it always interferes. A high db reading of emi shielding is good. Electro-magnetic waves are present everywhere and the problem is keeping them out of our electronics as best as we can. An additional problem is that all electronics produce electro-magnetic fields.
