The main visible specialization for absorption of substances in intestinal cells is the presence of microvilli, which are tiny, finger-like projections on the surface of enterocytes. These microvilli significantly increase the surface area of the intestinal lining, enhancing the absorption of nutrients. Additionally, they are covered by a glycocalyx that contains enzymes and receptors, further facilitating the uptake of substances. This specialized structure is crucial for efficient nutrient absorption in the digestive system.

Calorescence is the absorption of infrared radiation and emission of visible light.
The wavelength of visible absorption typically ranges from about 380 nanometers (nm) to 750 nm. This range corresponds to the visible spectrum, which includes violet (around 380-450 nm), blue (450-495 nm), green (495-570 nm), yellow (570-590 nm), orange (590-620 nm), and red (620-750 nm) light. Different substances absorb specific wavelengths within this range, which is why they appear in various colors.
Chlorophyll and carotenoids are substances that can absorb visible light in plants. Additionally, dyes and pigments used in various applications can also absorb visible light, leading to their characteristic color appearance. Metamaterials and semiconductor materials are examples of inorganic substances that can be engineered to absorb visible light for specific purposes.
Quantum transition for the UV-VIS absorption refers to taking the electron transitions associated with visible and ultraviolet.
The absorption spectrum of boron typically shows strong absorption in the ultraviolet region, with some absorption in the visible spectrum as well. Boron's absorption spectrum is characterized by a series of sharp peaks due to transitions between energy levels in its atomic structure.
The highest absorption in the electromagnetic spectrum includes gamma rays, X-rays, and ultraviolet light. Next comes visible light, followed by infrared, microwaves, and radio waves with the lowest absorption.
UV has higher energy (per photon) than visible light.

Visible vapor from burning substances consists of particles and droplets that have condensed from the gaseous state to form a visible cloud or plume. This is typically a mixture of partially burned or unburned fuel, along with combustion byproducts such as soot and ash.
Hypochromic shift is observed in UV VISIBLE spectroscopy. This is the shift where the intensity of the absorption maxima is decreased
