It is certainly possible to generate electric and magnetic fields that are out of phase, but they wouldn't radiate as a source-free wave in vacuum, so I wouldn't call it "light".tigor said:is it possible to generate light with phase shift between fields ?
cmos said:If you propagate light through a lossy material (i.e. absorption occurs), then, in general, the electric and magnetic fields will be out of phase.
cmos said:Born2bwire:
For harmonic waves (time and space), B is proportional to kxE. In lossy media, k is complex. Therefore, B has an additional phase factor with respect to E.
An electric field is a physical field that surrounds an electrically charged particle or object. It is created by the presence of a charged object and exerts a force on other charged objects within the field.
A magnetic field is a physical field that surrounds a magnet or a moving electrically charged particle. It is created by the movement of electric charges and can exert a force on other moving charges within the field.
Electric and magnetic fields are closely related and are often referred to as electromagnetic fields. When an electrically charged particle moves, it creates a magnetic field. Similarly, a changing magnetic field can create an electric field. This relationship is described by Maxwell's equations.
The speed of light is a fundamental physical constant that represents the speed at which light travels in a vacuum. It is approximately 299,792,458 meters per second (m/s).
Electric and magnetic fields can interact with each other through a phenomenon called electromagnetic induction. This occurs when a changing magnetic field induces an electric current in a nearby conductor, or when a changing electric field induces a magnetic field. This interaction is the basis for many technologies, such as generators and transformers.
