I am confusing about it that what are electromagnetic field books said that it does not require medium then how they propagate in vacuum and we also know that waves are disturbance through a medium
Orodruin said:Electromagnetic waves are disturbances in the electromagnetic field. They do not require any medium to propagate in.
To some extent, yes. The reason I do not want to talk in that fashion (in particular with laymen) is that it risks creating a confusion, namely that there is something called "field" that is actually being displaced (as transversal or longitudinal displacement waves in a medium).jtbell said:I would say that the electromagnetic field itself is the medium that they propagate in. When we talk about water waves propagating through water, we don't feel the need to invoke some other medium, do we?
Do you know how to take derivatives or integrals? Are you familiar with differential equations, or vectors, or partial differential equations?Aafia said:About what ??
Electromagnetic waves are a type of energy that can travel through space. They are created by the movement of electrically charged particles and are composed of both electric and magnetic fields.
Unlike mechanical waves, such as sound waves, electromagnetic waves do not require a medium to travel through. They can also travel at the speed of light and have a wide range of frequencies and wavelengths.
The electromagnetic spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of wave has a different frequency and wavelength, and they are used for various purposes, including communication, heating, and medical imaging.
Electromagnetic waves are produced when an electrically charged particle, such as an electron, vibrates or accelerates. This movement creates a disturbance in the electric and magnetic fields, resulting in the emission of energy in the form of electromagnetic waves.
Electromagnetic waves have a wide range of practical applications in our daily lives. They are used for communication, including radio and television signals, as well as for cooking and heating in microwave ovens. They are also used in medical imaging, such as X-rays and MRI scans, and in technologies like GPS and radar.
