Optical tunneling
Optical tunneling is demonstrated by frustrated total internal reflection.
- A green laser diode (from a laser pointer) falls on a
Demonstrating diffraction of light
With a helium-neon laser, we can demonstrate the diffraction of light from a single slit, double slit pattern or from
X-rays as probes of atomic structure
X-rays are produced when inner shell transitions take place inside atoms. This demonstration uses 
an X-ray tube, X-ray
detector and
