Answer 1

10 entries found for light.
light1 ( P ) Pronunciation Key (lt)
n.

Electromagnetic radiation that has a wavelength in the range from about 4,000 (violet) to about 7,700 (red) angstroms and may be perceived by the normal unaided human eye.
Electromagnetic radiation of any wavelength.
The sensation of perceiving light; brightness: a sudden light that made me blink.

A source of light, especially a lamp, a lantern, or an electric lighting fixture: Turn out the lights when you leave.
The illumination derived from a source of light: by the light of the moon.
The particular quantity or quality of such illumination: moved the lamp closer to get better light.
The pathway or route of such illumination to a person: You're standing in his light.
A mechanical device that uses illumination as a signal or warning, especially a beacon or traffic signal.

Daylight.
Dawn; daybreak.
Something, such as a window, that admits illumination.
Architecture. One of two or more openings in a window divided by a mullion or mullions.
A source of fire, such as a match or cigarette lighter.
Spiritual awareness; illumination.

An expression of the eyes: a strange light in her eyes.

Answer 2

Quantum of light is a particle and wave simultaneously.
Exact there is a simultaneity of space and time.
For me such explanation is unsatisfactory.
It just as to speak, that the logic information and
the senseless message are the same simultaneously.
To say half truth is worse then to say lie.
* * *
Quantum of light is a privileged particle.
Only the speed of a light quantum has
a maximal, constant, absolute quantity of c=1.
No other particle can travel with the speed c = 1.
If quantum of light flies always rectilinearly c=1, it is a mad one.
Is he really mad?
* * *
Only a light quantum has the absolute speed c=1.
No other particle can travel with the speed c = 1.
Other particle can travel with the speed v=s/t only.
And I was taught at school from the first class:
that the incommensurable quantities cannot be compared.
To connect incommensurable quantities it
is similar to the decision of a problem:
“What will be if the whale will attacks the elephant?”
====================================
On the question:
What inhale the Life in formulas and equations ?
What must be present in a body to make it alive ?
The answer is:
Soul. Quantum of Light.
Because, from all particles, only and only
the quantum of light is a privileged particle.

Answer 3

The electromagnetic wave that is visible to our eyes is called light. Its wavelength ranges from 4000 to 7000 angstroms. Light is considered to be dual in nature because it consists of particles or photons that propogate along a straight line in the form of waves.

Answer 4

Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific context, electromagnetic radiation of any wavelength.

Answer 5

superb suited now, i'm too lazy to make the variations regarding freedom that could desire to be made. case in point, there is political freedom which differs from volitional freedom. with the aid of "political freedom," I propose that kind of liberty which governments enable electorate to have. Volitional freedom refers to what's usually called unfastened will, which would be added well known with the aid of ability of the countless kinds "freedom of indifference" and "freedom of spontaneity." Then we've religious freedom. that's the place i discover genuine liberty. Freedom is that figurative locus wherein the spirit of God is residing; for the place God's spirit is, there is liberty (2 Corinthians 3:17).

Answer 6

Light is an electromagnetic wave in which the mass less particles called photons vibrate at their mean position.

Answer 7

actually light is a Electromagnetic radiation.

it has a wavelength in the range from about 4,000 to about 7,700 angstrm. and is visible by human eye.

Answer 8

light is radiated energy. It has a specific wavelength (around 4000-7000 angstroms I believe)

You eyes are constructed to respond to radiation in that spectrum and your brain gets the signals.

Shorter wave lengths (higher frequency) are ultraviolet, X-rays, and gamma rays. Longer wave lengths (lower frequencies) are infared, microwaves, cell-phone frequencies, TV, FM, AM

Answer 9

light is visible energy.
