I've been doing a little research on the properties of light as it pertains to dating. Here's what I've found.

In the begining, God said, "Let there be light." And there was light.

In the year 1666, Isaac Newton focused a beam of light at a prism separating it into the visible spectrum. Between 1704 and 1730 he publishes Opticks, where he develops the particle theory of light. He is able to give plausible explanations for properties of light such as color, reflection, and refraction. Visible light contains all colors naturally, but there are three main or primary colors. Red, blue and green. Using just those three colors, all the other colors can be created by mixing them in different ways. Red and blue create magenta, red and green make yellow, blue and green make cyan. Those are called the secondary colors and can be mixed in the same way to recreate the three primary colors.

Years later, in 1819, Augustin Fresnel writes a comprehensive treatment of the wave theory of light, refuting completely the particle theory of light.

In the early 20th Century, German scientist Albert Einstein proposed that light has the properties of both particulates and waves. We have all heard the equation E=mc2 where E is the energy, m is the mass of the body and c is the velocity, or speed, of light. That famous equation explains that mass and energy can be converted from one to the other. In metric units, the speed of light is exactly 299,792,458 metres per second (1,079,252,848.8 km/h). The fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299,792,458 of a second.

Let us consider the differences between a wave and a particle.

Particles are discrete. Their energy is concentrated into a finite space, one which has definite boundaries and homogenous contents that are the same at any point within the particle. Particles exist at specific locations, represented by a set of as many co-ordinates as there are dimensions, each co-ordinate representing one. Particles can never exist in more than one places at the same time. Their motion is governed by the the laws of kinetics and mechanics. Simple laws like the law of conservation of energy and the law of conservation of momentum govern how particles interact during collision. These essential basic laws are a part of Newtonian mechanics and were first published in his principia mathematica in 1687.

Waves, on the other hand cannot be considered a finite entity. Since by definition, the energy of waves varies both in dosplacement as well as time, their energy cannot be considered to exist in a single place.

A wave, unlike a particle can propagate, in an area of space until it exists in all locations and at all times. A pure sine wave is to represent a wave in nature mathematically. Such a wave has no beginning or end, a fixed period after which it repeats itself. Hence, we just need to analyse a part or a phase of the wave and obtain a value for its velocity within this area. Some fundamental features that govern the nature of a wave are the frequency (f), wave number (k) and wavelength (8).

Light is a deformation of electric (E) and magnetic (B) fields in an area of space, which oscillate in planes that are perpendicular to each other.

These two known ways in which the transmission of energy occurs - waves and particles seem to be completely different from each other. However, both of them perfectly seem to befit the title - 'component of energy.

My conclusion of this research is that when the wave-particle duality of light bounces off a womans cleavage, and reflects into my eyes, I am powerless to stop it.

So, does this mean that you've seen the light?smokin drinker bigsmile
