Want to know how the eye focuses or accommodates? This video goes through the physics of accommodation, how the eye adjusts in order to produce a sharp image on the retina. It also covers long and short sightedness and how to fix them.
This video covers how crystals are used to create and receive high frequency sound. Apart from their use in small speakers, they are especially useful in their used of transducers for ultrasound imaging.
A follow up of my first video on circuits, this video explores the mathematics. of circuits, with the use of Ohm’s Law to determine resistance, voltage and current, in both series and parallel circuits.
In this video I review the famous Michelson Morley experiment, what is known as the most famous null result experiment. Although impossible to reconcile with the understating of Physics at the time, it became fully understood in the context of Einstein’s Theory of Special Relativity. I use a couple of useful analogies to help you understand the experiment.
A video that demonstrates the Meissner Effect. Produced with the Australian HSC in mind. This does abruptly end as I had to remove an erroneous section. Nonetheless, it’s the meissner effect that causes levitation. Any further explanation for the stability of the levitation is Quantum related and beyond the school of a high school student.
