When white light is shone on red ink dried on a glass plate, the color that is transmitted is red. But the color that is reflected is not red. What is it? Explain.
(
Why?
From fireworks to stars, the color of light is useful in finding out what's in matter. The emission of g
by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms.
Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be
identified by heating or burning the materials and examining the color(s) of light given off in the form of
bright-line spectra.
