Difference between Interference and Diffraction: This article covers an important topic from Class 12 Physics. As we all know, Physics is one of the toughest subjects in Class 12. With the vast amount ...

A device that breaks up an electromagnetic wave into its different frequencies (wavelengths) by scattering them at different angles. For example, a series of thousands of scored lines in a glass plate ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th century, scientists realized it was both: massless particles and waves. An even ...

Two independent groups of physicists have found a new way to get high-definition glimpses of the innards of living cells. The technique uses X-ray diffraction microscopy on cells frozen below –170 °C, ...
