In fact, considering the number of ways that light-induced chemical reactions can wreak havoc ... such as dyes, inks, pigments, varnishes, and oils, as well as the materials they're used on ...

Plants can perceive light and heat via so-called phytochromes and use these pigments to trigger vital reactions such as growth. Climate change and steadily rising temperatures can disrupt plant ...

There is no such thing as “black light wavelength”—so why do black T-shirts, black crayons, and black marking pens look black? Investigate a variety of black ink markers, and find out why they look ...

This stage is so-called because it depends on light being available. The reactions of this stage also require specific enzymes to catalyse them. Light energy absorbed by chlorophyll is converted ...

Pigments reflect specific wavelengths of light to produce their color. The remaining wavelengths are absorbed, generating heat. Over time, chemical reactions occur in the pigments, causing color ...
