Far from being a solely quantum mechanical phenomenon, interference occurs with all kinds of waves, including water waves and sound waves. Interference is the process in which two or more waves of the ...

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

This story was originally written for and published by Drexel News. Researchers in the College of Engineering have developed a thin film device, fabricated by spray coating, that can block ...

One of the deepest mysteries in quantum physics is the wave-particle duality: every quantum object has properties of both a wave and a particle. Nowhere is this effect more beautifully demonstrated ...

The hallmark of a Bose–Einstein condensate is the existence of a well-defined macroscopic phase. Indeed, experiments with large condensates exhibit robust matter-wave interference with negligible ...

The absorption of electromagnetic energy by a material is a phenomenon that underlies many applications, including molecular sensing, photocurrent generation and photodetection. Typically, the ...

Horizontal transmitting aerials may be used at medium frequencies for short-distance broadcasting via the ionosphere. The use of horizontal rather than vertical aerials affects the strength of ...

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...
