Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross-section. Then, an electromagnetic signal (blue wavefront) was injected from the right to extract information about ...

In this video, we dive into the reflected and transmitted waves on a string—a fundamental concept in electrodynamics and wave physics. Using clear examples, we explore how waves behave when they ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

Down at the level of atoms and electrons, quantum physics describes the behavior of the very smallest objects. Solar panels, LED lights, your mobile phone and MRI scanners in hospitals: all of these ...
