I love this activity and have used it for a couple of years, except I've realised there is a flaw which could introduce misconceptions, and so I think I'll stop using the activity. The colours of the smarties imply that photons in the visible range of the EM spectrum are emitted; however, this only happens in the Balmer series, where electrons relax from the other energy levels down to n=2.

Agree that is a danger - perhaps we could add some transparent-ish coloured sweets in to the model to represent UV? e.g. some kind of haribo?

The rapid condensation of water steam inside the can causes almost immediate vacuum when the steam turns into liquid water on the surface of cold water in the bowl. This explains why the volume of air inside the collapsed can is nearly zero

1:20 you wrongly altered the simulation which would result in the visualization of the actual phenomenon called "skin effect."

@DanCottle1 5 ай бұрын

Thanks for your comment. I agree that leaving out the side pieces would provide a good model for the skin effect of conduction! However, this model is intended for use in early secondary education and at this level concepts of electron drift leading to explanations of current flow and resistance are what was being aimed at. It does show that the model could be extended though!

thanks for this if i wanted to increse the emf at 15khz how would i do that would i need more windings or just more power or is 15khz a fixed emf amout ?

@Mechanarian Ай бұрын

To increase emf you would need a stronger field or more windings

@@deadlinkofficialartst5592 It's not. I use these regularly and all they have is a knob for frequency and some switches to choose the waveform type. There is an output amplifier state but ehh. The frequency stability on these isnt very good but sure you could use it as a VCO as part of a synth if you really wanted, although the size of this thing makes it pretty impractical.

I have a sun allergy called Solar Urticaria. I'd like to investigate which wavelengths trigger the reaction. I was thinking of building a similar prism and simply using sunlight instead of the projector\Fresnel lens. I'd then cut a slit in some cardboard to isolate specific colors and stand on the other side to expose my skin. Can you think of any problems with this plan?

@rudylosavio6626 7 ай бұрын

Interesting !! If i may suggest someting, also try to maks what you can't see : infrared and ultraviolet, on each side. Il you are going to concentrate the light before the prism, the effect of UV (invisible) can be quite intense and bad for your skin /eyes
