The phrase "a gap of light" is correct and usable in written English.
It can be used to describe an opening or space that allows light to pass through, often in a physical or metaphorical context.
Example: "As the storm clouds parted, a gap of light illuminated the valley below."
Alternatives: "a beam of light" or "a ray of light".
Similarly, a pigeon will learn to peck at a disk illuminated with red light even if a gap of several seconds separates this response from the delivery of food.
Most successful regeneration takes place where gaps of light reach the forest floor.
An analysis of the optimal band gaps of light absorbers in integrated tandem photoelectrochemical water-splitting systems.
Cregan, R. F. et al. Single-mode photonic band gap guidance of light in air.
One of the prime characteristics of a photonic crystal is that it has a band gap -- a range of light frequencies that is not propagated within the crystal, but rather reflected.
This is a significant gap in light of an aging demographic with multiple complex chronic illnesses and economically induced migration patterns that include older adults retiring in rural areas for financial benefits and younger adults leaving rural areas because of declining employment in resource dependent industries [ 4].
A small gap in a window allows a ray of light to shine through into the church, and during the winter solstice, at midday, the beam of light illuminates a brass line on the obelisk at the far end of the church.
When the light is incident on the surface of 3D nanorods, the photons will be reflected back and forth between the nanoscale gaps resulting in an increase of light absorption (Scheme 1).
To ascertain if quantum confinement affects the energy gap of a-Ge QWs, light absorption spectroscopy was performed in the samples grown on quartz substrates.
We do not mean to suggest that this classification is better than any other, but we are suggesting that an empirical approach, independent of a priori classification, can be very useful in light of a gap in understanding the biological effects of simultaneous exposure to multiple congeners in different proportions.
