Our understanding of how light behaves has grown with the surprising discovery that colors can be seen in a new way; an example of a process called scattering, the effect occurs in some materials when ...

We explore double and single slit example problems involving light and sound waves. In this Closer Look segment on Diffraction and Interference, we explore double and single slit example problems ...
