In the simplest of terms, a wavelength is a frequency of electromagnetic energy. At the most basic level, this means that in a vacuum, only a frequency of electromagnetic energy, the zero frequency, is at the same wavelength as the vacuum. For that reason, a vacuum is a zero-frequency space.
The problem is that, much like the concept of light, a vacuum does not exist in the same dimension. In a vacuum, you can only see a frequency of electromagnetic energy that is a very small fraction of the vacuum’s wavelength, or the zero frequency. To truly see something in the vacuum, you need to be in a very small chunk of the vacuum’s wavelength.
We’ve all been on the receiving end of a vacuum in one way or another. A couple of weeks ago my friend told me his vacuum-induced hearing loss was the result of the vibrations of the air from a vacuum pump. Another friend’s vacuum-induced migraine headache was the result of his “clicking” while he was sleeping.
The concept of energy is very complicated. The most general definition of energy is the motion of matter, but that doesn’t really help us with the issue of wavelength. In fact, the entire concept of “energy” is a lot trickier than that. The word actually comes from the Greek words for “energy” and “motion.” This is important because the concept of energy is not limited to the kinetic energy of a particle (e.g.
The concept of energy is related to the idea that energy is the ability of a system to do work. In physics, energy is a measure of the energy required to convert a chemical to a form of energy. The energy is measured in joules, which are roughly equivalent to the energy required to change one joule of kinetic energy. Therefore, the energy of a molecule is the amount of energy needed to change one joule of kinetic energy.
The energy in a molecule can be converted into photons, which are the same energy units as photons. Each photon has a wavelength, which is the distance of the photon from an electron or proton. The wavelength is the fundamental unit of measurement in physics. So, photons are the same units as energy.
Photons are the fundamental unit of measurement in physics. However, there are several other units of measurement that physicists use to describe the properties of photons: energy, wavelength, wavelength squared, and wavelength cubed (where wavelength squared is the fundamental unit of measurement for energy, and the energy is the fundamental unit of measurement for wavelength).
The units for energy are Kelvin (i.e. the number of joules of energy per second and the unit of measurement for pressure), Joules, and Volt.
The energy is like the energy in a car battery and the unit of measurement is joules per second. However, not every photon can be measured at the same time. The energy of one photon is measured at one particular wavelength in one particular time interval, and therefore there is a relationship between wavelength and energy.
The relationship between wavelength and energy is one where, if there is an atom of energy, it will be in the form of a particular wavelength. The photon, being a stream of energy, is not in the same form and therefore cannot be measured at a single wavelength at one particular time. It is therefore the wavelength of the energy that is measured at one particular time.
