Pressure undulates,
Rippling materials-
Excluding ether

#PCZ223 I created a thin film interference with bubbles!! Light reflects off both sides of the bubble fim which creates a beautiful rainbow

Candles float!! Who knew?? As you can see, the submerged portion of the candle displaces the same mass of water as the whole candle!

These are prism stickers and they cover my room in rainbows when the sun sets! White light is separated into a spectrum of color as it refracts through the medium and turns into a rainbow!

#PCZ223 I created superimposed waves in my sink with two crystals bobbing up and down! I dyed the water so you can see the shadow of the waves (:

Thank you for everything you gave me, good sir. Your calm demeanor never masked your fire for teaching and learning

#PCZ222 Solid state batteries are made of solid electrolytes - engineered semiconductors have 'holes' that allow ions to move within the battery very quickly, removing the risk of liquid electrolytes (explosion, dendrites) while maintaining the benefits!!

#PCZ222 this is a wireless phone charger that uses an inductor to create an electromagnetic interaction! Current cannot pass directly from charger to phone so a magnetic field is induced in the inductor in the charger that induces current in the battery, allowing it to charge!!

Needle's deflection
Caused by EM force. Coils of
Current magnetize.

#PCZ222 this fourteen (!!!) year old boy invented a device that absorbs the impact energy from falling hail, snow, and rain on rooftops and converts that into usable electricity using something called called a piezoelectric device!

Heavy snow causes powerline 'arcing' which occurs when snow causes the potential difference across the line to become so great that we see electrical breakdown- like across capacitor plates- and we see a flash as the breakdown threshold is reached

#PCZ222 Check out this super cute video where a lil scientist named jojo explains how we can use thermal differences - instead of potential differences - to power a motor with an ice cube and a peltier device (:

@ProfZirul Hey Prof may we please have a point grab! Hope ypu stay warm today in your 'winter attire' 🤣🤣

The organic chemistry tutor is my favorite guy for physics videos! I like this video especially because he gives a good introduction at the beginning before doing some example problems that help me visualize Gauss' Law.

Both ways. Moments follow the
Direction of field

#PCZ222 These pieces of tape are repelling due to static electricity!!
