Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same ...

In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

Refraction is explained by looking into a pool and seeing Snell's law in action. We also explore the concepts of total internal reflection and formation of the critical angle. Plan and carry out ...

The law of reflection is introduced as we learn about the difference between specular and diffuse reflection and discover the difference between real and virtual images. Plan and carry out ...
