This project delves into the principles of interference, particularly focusing on how light waves interact with very thin films, like those seen in soap bubbles or oil slicks. The post is in ...

Young's experiment showed interference of light. As only waves demonstrate interference, this confirmed that light was a wave motion not a stream of particles. Watch this video for a practical ...

One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

A new study has achieved unprecedented precision in detecting tiny shifts in light displacements at the nanoscale. This is relevant for example in the characterisation of birefringent materials and in ...
