A transverse wave is a wave which makes the particles it passes through vibrate up and down.

We say that the vibrations are at right angles to the direction of wave travel

Examples of transverse waves are waves on a string, S-waves in earthquakes.

Play the above movie and watch how the particle moves as the wave passes.

You can also measure the period T of the wave and if you measure the wavelength you can work out the wave speed.

You will be given a warning that the exe file is potentially dangerous but in this case it is safe.

This problem appeared in the 2014 Physics Higher & Revised Higher. Here is the worked solution.
The solution involves scale diagrams…ugh and of course vector addition.

Hi Physics students! Here is the video of my second Google Hangout.

This movie shows how the radioactive count rate is affected by placing material of certain thicknesses in front of a radioactive source.

Hi Physicists here is the first Google hangout which I gave this morning.
Great to work with talented tech savvy pupils.
Apologies for my calculation error, well spotted physics students.
Sorry for the mix up at the end when I tried to get back from screenshare and a thanks to Martin Cunningham for use of his notes.
