what is light?

Question

the kind of light that you get from a lamp

Answer 1

Light is a form of electromagnetic radiation. Energy can exist in many different forms (heat, sound, light, etc), so light is considered to be energy. Light was generally thought to be just a wave (of electromagnetic radiation), but it also exhibits characterisitics of particles. For that reason, light can be thought of as a combination of electromagnetic radiation waves, and a stream of particles called photons. All this information applies to ALL kinds to lights, INCLUDING the light that you get from a lamp.

Answer 2

Light is the visual part of the electromagnetic spectrum that lies between the infra red (very long waves) and the ultra violet (very short waves) at both ends.

From a lamp, we get not only the visible light, but also heat in the form of infra red radiation due to the fact that the filament is heats up due to the electricity passing through it. Most lamps emit a yellowish color though it is possible to make lamps that emit a wide variety of colors.

Answer 3

The electrical energy passing through a tungsten filament in a vacuum filled bulb, causes the filament to give out an incandescent form of energy called 'LIGHT' together with heat.

If it's an oil lamp, the wick draws up the oil and, when ignited the oil vaporises and burns giving off light, heat and combustion gases.

Answer 5

Light is a form of energy which gives a sensation of sight to eyes. It enables the eyes to see objects by the light the objects reflect or shadow.

Light is a part of the electromagnetic spectrum. Some restrict "light" to what humans can detect with our eyes but many scientists simply use the word light to mean any and all forms of electromagnetic radiation. To refer to light we can see, they often use the adjective "visible".

Electromagnetic radiation is particle-waves. It possesses properties of both particles and waves. It has both a vibrating electric field and a magnetic field, each at right angles to the other and at right angles to its direction of travel. It is always travelling at a speed of roughly 2.998 x 10 8 metres/sec. Experiments with the photoelectric effect shows energy is transferred between atoms in discreet packets of energy suggesting a particle nature. In any case, "waves" and "particles" are only abstractions we use to visualise what we can't imagine because it is outside of our normal frame of reference.

(*Light travels through transparent materials at a slower rate of speed, according to the material's refractive index.)

Answer 6

Ah ok, I misunderstood your last question.
That kind of light is a form of energy.

Answer 7

Energy.

Answer 8

a photon that moves at 300,000,000 meters per second in a vacuum, and cannot be made to go faster or slower(unless passed through something)

Answer 9

Electric and magnetic fields working in harmony.

Answer 10

One day it is waves and next day it is corpuscles. It all depends on what day of the week it is and also which scientist you are talking to!!
