cathode rays are electromagnetic waves?

Originally Answered: Cathode rays cannot be regarded as electromagnetic waves. ... Cathode rays are beams of free electrons that project electric and magnetic forces as they travel, which are mistakenly called 'waves'.

Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called "electromagnetic radiation" because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances.

They are both waves, so yes. Electromagnetic waves are obviously waves made up of an electric field that is oscillating and a magnetic field that is oscillating. One unique characteristic it has is that it doesn't need a medium to travel in (it can travel through space). Sound on the other hand is a vibrational wave.

Electromagnetic waves are generated by moving electrons. ... In turn, the moving electron generates a magnetic field that will also become wavy from the motion of the electron. These combined electrical and magnetic waves reinforce one another. This kind of wave is called an electromagnetic wave and light is such a wave.

Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. ... Since the electrons have a negative charge, they are repelled by the negative cathode and attracted to the positive anode. They travel in straight lines through the empty tube.

Electromagnetic waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel.

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

The term also refers to the emission and transmission of such radiant energy. Radiation is all around us. ... Electromagnetic radiation is "energy" that is propagated through the vacuum of space or through a material medium in the form of waves - like radio waves, light waves, X-rays and gamma rays.

Electromagnetic waves are waves that contain an electric field and a magnetic field and carry energy. They travel at the speed of light.

Electromagnetic waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel. All electromagnetic waves: transfer energy as radiation from the source of the waves to an absorber.

Electromagnetic Radiation. Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.

electromagnetic waves are a type of mechanical waves, specifically a transverse wave. they transfer energy. electromagnetic waves dont need a medium to travel through but mechanical waves do.

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not.

Which of these is the same for all forms of electromagnetic (E-M) radiation in a vacuum? ... Radio waves, visible light, and X-rays are all a type of electromagnetic radiation.

Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to render an image on a screen.

Definition of 'Electromagnetic Waves' Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
