James Maxwell was able to show that a vibrating charge would result in the propagation of an electromagnetic wave that would travel with velocity that "just happened" to be the speed of light. Since that time, repeated tests have shown that every prediction resulting from the idea that radio waves, light waves, and x-rays (amongst others) are examples of this EM wave have turned out to be correct.
Light is considered to be an EM wave because every test of that statement has given a positive answer.
That is, until, quantum theorists were able to show that light travels in discrete chunks of energy now called "photons."
What else can I help you with?
Why is light considered an electromagnetic wave?
When it was determined that light exhibits all of the properties of wave motion, including refraction, reflection, diffraction, and dispersion, and that its speed is exactly determined by the electrical characteristics of the medium through which it propagates, just like radio, heat, ultraviolet radiation, X-rays, and gamma rays, and as predicted by the wave equation that Maxwell derived from the properties of electricity and magnetism, it then began to dawn on cutting-edge researchers that light is also an electromagnetic wave. In short, the answer to the question "why" is: Because it IS one.
What is the definition of electromagnetic wave?
An electromagnetic wave is a type of energy wave that consists of vibrating electric and magnetic fields propagating through space. These waves carry energy and information through a vacuum or a medium, and they travel at the speed of light. Examples of electromagnetic waves include radio waves, microwaves, visible light, X-rays, and gamma rays.
Why are light and sound not considered to be matter?
light and sound do not have mass. Light is electromagnetic wave transverse in nature. Sound is longitudinal wave. But sound needs material medium so it is mechanical wave. Moreover matter is the one which occupies the space. But waves do not occupy but traverse in space. Electromagnetic waves don't need material medium, but sound waves do need a material medium. False physics to assume that light has no mass. Energy = mc^2 =hf=cp. Light has energy and momentum. p=h/w =mv.
What has particles that vibrates at right angles to the direction of the wave?
Photons oscillate (vibrate) along an axis that is perpendicular to the direction of the photon's travel. Photons are responsible for all electromagnetic radiation, including visible light, invisible light (infrared and ultraviolet), X-rays, radio waves, and magnetic waves. . When all photons in a beam of light oscillate in same direction, that is called polarized light.
A wave whose energy travels the same way as it was transferred?
A transverse wave is a type of wave where the disturbance moves perpendicular to the direction of energy transfer. This means that the energy travels in the same direction as it was transferred. Examples of transverse waves include light waves and electromagnetic waves.
What is electromagnetic rays?
In old concepts light wave had been considered as light ray. Same way electromagnetic wave is considered as electromagnetic ray.
Is light considered a electromagnetic wave?
Light is said to be of dual nature so it has particle nature as well as wave nature but there is a difference in waves and electromagnetic waves. so ,as for your question "Is light a electromagnetic wave" the answer is "no"More precisely, if visible is not an electromagnetic wave, the NO part of the electromagnetic spectrum could be considered to be an electromagnetic wave. By any definition of the term, the answer is 'Yes'
What type of wave is a light wave an example of?
Light is an example of a electromagnetic wave.
Is the light wave electromagnetic or no?
The light wave is electromagnetic yes.
Is light an electromagnetic wave?
Yes, light is an electromagnetic wave.
What kind of wave is light considered?
Light a general term for a specific range of wavelengths in the electromagnetic spectrum, is not strictly just a wave, it shows particle and wave like properties, hence it being able to travel in a vacuum without a medium. However as a wave light is considered to be a transverse wave.
What is the name of the wave that deals with light?
An electromagnetic wave.
Is light a mechanial wave or an electromagnetic wave A tranverse wave or a compressional wave?
electromagnetic, transverse
What kind of wave does light travel as?
Light is an electromagnetic wave.
What is relation between light and electromagnetic waves?
Light is an electromagnetic wave.
Is light considered static electricity?
Light is not electricity; it is an electromagnetic wave. It is anything but static; the speed of light is 186,000 miles/sec.
What types of wave is a light wave?
I believe that it is an electromagnetic wave?
