Atomic Models - free
1. Schrödingers model predicts that the energy of an atomic electron is equal to -k/n2 where k is a constant and n an integer. If the energy required to take an electron... more»

1. Given that the resolving power of a microscope is proportional to the 1/wavelength of radiation used, show that if 600nm light is replaced with electrons accelerated through a Pd of 40,000V... more»

1. A filament lamp gives out light of average wavelength 600nm when connected to a 220V supply. The current flowing through the filament is 5A (rms). If 3x1020 photons are emitted per... more»

Another failure
Posted on 24 January 2012
This morning I wrote a problem sheet for my HL students on the photoelectric effect. The first question was about a filament lamp so I illustrated it with a photo of the lamp behind my head. I was interested to... more»

Today I was introducing single slit diffraction to my SL class and was having difficulty showing how the phase changed as you increased the diffracting angle. I was trying to do it on the SMART board and could get an... more»
Being negative for the sake of it
Posted on 22 January 2012 by Chris Hamper
The other day in class I was deriving the equation for the simple pendulum and started wondering how to make the solution negative. I knew it had to be to fit in with the result a= -ω2x but why should... more»
Monthly Feature
It's always worth having a look at the "new sims" on the Phet site. They have been busy producing some for Chemistry and Biology but also a couple of new one for physics. With so many good applets and animations around it's worth making yourself a page of links. I started one some years ago and it's now part of this site. I have organised the links in under IB syllabus headings, here is the page for the core.
I find it so difficult to remember what the link is from the URL so have included a thumbnail screenshot to help. If I were making this page today I'd embed the links from Phet instead.
States of Matter
This one shows the way the molecules behave as heat is added. What I'd like it to show is that the temperature doesn't change as the material changes state. This doesn't seem to be the case though.
Resonance
In this one you can set the properties of the springs to get resonance. I think I'd need to play with this one a bit before using it in front of the class as it seems a bit fiddly.

Quote of the Day
“Physics is becoming so unbelievably complex that it is taking longer and longer to train a physicist. It is taking so long, in fact, to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them.”
