From 4 cm to ice bottom, the logarithms of radiance profiles almost decrease linearly with increasing the path length of light transfer.

Cold Regions Science and Technology

The periodically patterned photonic crystal based substrates achieve (1) high diffraction, enhancing the path length of light in thin absorber layers and (2) plasmonic concentration of light intensity.

Solar Energy Materials and Solar Cells

Decisions on the length of light guide which leads to optimum resolution have been made on the basis of experiment and Monte Carlo simulation of the photon transport within the cell and light guide, previously reported.

Radiation Measurements

Photoperiod, the daily length of light exposure, has a marked metabolic effect in both fishes and amphibians; fishes, however, remain active throughout the year, although the activity may be limited by temperature, as in those fish that rest on the bottom or in mud during cold periods.

Consider, for example, the fact that systems of very different physical constitutions (say a gas made up of molecules interacting by means of forces on the one hand and on the other hand radiation whose components are energetically coupled wave lengths of light) can share thermodynamic features.

SEP

The continuous oxy-Hb data were filtered with band-pass frequencies in the range of 0.01 0.2 Hz and were standardized (z-score) in order to avoid the methodological ambiguity that changes in absolute values of Hb concentration for each recording channel were not determined, because the absolute path lengths of light through the cerebral cortex were not detectable.

Plosone

Interference then occurred when the path lengths of light reflected from the sample and the reference mirror were matched to within the coherence length of the source.

Expert writing Tips

Best practice

When discussing the impact of light on biological processes like plant growth or circadian rhythms, clarify whether you're referring to the "length of light" exposure per day (photoperiod) or the duration of a specific light pulse.

Common error

Avoid using "length of light" when you actually mean "wavelength of light". Wavelength refers to the distance between peaks of a light wave, while "length of light" typically refers to duration or path length.

Linguistic Context

The phrase "length of light" functions primarily as a noun phrase, often acting as the subject or object of a sentence. It typically describes a measurable aspect related to light, such as its duration or path. Ludwig AI confirms its usability in written English.

Ludwig's WRAP-UP

The phrase "length of light" is a noun phrase primarily used to describe a measurable aspect of light, particularly its duration, path, or coherence. Ludwig AI indicates that it is a correct and usable phrase in written English. While most frequently found in scientific and technical contexts, its use extends to encyclopedic and news reporting. When using this phrase, be mindful of the specific dimension of light you're describing—duration, path, or coherence—and consider alternatives such as "duration of light exposure" or "optical path length" for greater clarity. Avoid confusing it with ""wavelength of light"", which refers to the distance between peaks of a light wave.

FAQs

How does "length of light" relate to photoperiod?

In biological contexts, "length of light" often refers to photoperiod, which is the daily duration of light exposure that influences various physiological processes in plants and animals. It's about the hours of light in a 24-hour cycle.

When should I use "path length of light" instead of "length of light"?

"Path length of light" is more appropriate when describing the distance light travels through a specific medium, like in optical experiments or atmospheric studies. It specifies the actual trajectory of light rays.

What's the difference between "duration of light" and "length of light"?

While similar, "duration of light" is generally used to express how long a light source is active. "Length of light" can also imply the distance light travels or a physical dimension related to light, though duration is a common interpretation.

How does the "length of light" affect plant growth?

The "length of light" or photoperiod significantly impacts plant growth, flowering, and other developmental processes. Different plants have different light requirements, with some needing longer day lengths and others needing shorter day lengths to thrive.
