why electromagnetic waves cannot be deflected by magnetic field?

All electromagnetic waves have the electric and magnetic fields vibrating perpendicular to each other. ... The quantum theory shows that light is made up of photons which do not carry charge, during to which it is unaffected by electric or magnetic fields.

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Explain how an electromagnetic wave can travel through space that contains no matter. An electromagnetic wave is made of vibrating electric and magnetic fields that continually induce each other; matter is not needed for this to occur. ... No; No; they have to move to produce a wave.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.

Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.... Electromagnetic waves can be described by means of vibrating electrical and magnetic fields which are mutually perpendicular. The nature of these waves is transverse.

Unlike a magnet's effect on metals and other magnets, magnetic fields don't attract or repel ions, but they can deflect ions under certain conditions. The ions must not only be moving, they must move on a path perpendicular to the magnetic field.

An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.

An electromagnetic waves is propagated by the oscillations of the electric and magnetic fields. A changing electric field produces a changing magnetic field and a changing magnetic field produces a changing electric field. Thus, an electromagnetic wave is self propagating and does not need a medium to travel through.

Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.

Propagation of an Electromagnetic Wave Electromagnetic waves are waves which can travel through the vacuum of outer space. ... Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge.

ELECTROMAGNETIC WAVES Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves.

These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. ... Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. ... The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. They are also perpendicular to the direction of the EM wave.

EM waves do not propagate in a medium, whereas mechanical waves need one to exist. For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

Originally Answered: Cathode rays cannot be regarded as electromagnetic waves. Why? Because they are electrons. Electrons are (like all particles) also waves, true, and they certainly interact electromagnetically, but EM waves are made only of photons.

Electromagnetic waves are waves which can travel through the vacuum of outer space. ... Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.
