what kind of wave is light electromagnetic?

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.

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.

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. This vibration creates a wave which has both an electric and a magnetic component.

When most people use the term light waves, they usually mean visible light. In physics however, the term light waves tends to be used as a synonym for electromagnetic waves. ... From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.

Electromagnetic radiation, in classical physics, the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves, visible light, and gamma rays.

Terms in this set (42) An electromagnetic wave is a transverse wave. The energy carried by an electromagnetic wave is called radiant energy. All electromagnetic waves travel at 300,000 km/s in the vacuum of space.

Water waves and sound waves are examples of mechanical waves. Light waves are not considered mechanical waves because they don't involve the motion of matter. ... Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave.

Transverse waves can be mechanical or electromagnetic in nature. A mechanical wave is a disturbance that travels through a medium, such as a vibrating string. In contrast, an electromagnetic wave, such as light or radio waves, doesn't need a medium and can travel through empty space.

All electromagnetic waves move at the speed of light. Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. ... Radio waves are used for communications and radar. Microwaves are used to cook your food.

Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes.
267518
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.

The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy. This energy can be described by frequency, wavelength, or energy. All three are related mathematically such that if you know one, you can calculate the other two.

Unlike mechanical waves, which require matter, electromagnetic waves can travel through empty space, as well as through liquids, solids, and gases. There are many similarities between light waves and mechanical waves. They can both be measured by their amplitude, wavelength, and frequency. ... Mechanical Wave.

Electromagnetic waves. 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.

Sound travels in waves and exists only within a medium. Light also travels in a wavelike manner but light has electric and magnetic properties and accordingly it is an electromagnetic (EM) wave. Sound travels at 343 m/s in air and light travels through all mediums at almost 300,000,000 m/s.

Electromagnetic Radiation & Electromagnetic Spectrum This light, however, is only one type of electromagnetic radiation. Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum. The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.
