Hi Physics lovers!
Use the simulation above to find the frequency of the passing waves.
Press the UP Green arrow to start the wave motion. Pressing it again increases the wave speed while pressing the down arrow will reduce the speed.
If the waves run out just press the pause button and then the RESET button.

Make up a table with headings wavelength, frequency and speed and take some readings.

Check that wavelength multiplied by frequency is equal to the wave speed.

Use this table:
You can click on it and print it off.

PhET Projectile Experiment.

Use the PhET simulation sheet, there is a link below, to experiment with the cannon.

Link to PhET projectile site where you can download the virtual experiment or press run to have it on a bigger screen.

What happens to objects on transverse waves?
As the wave passes any object on the wave is moved up and down at right angles to the passage of the wave.

Check out how we can demonstrate this effect with a cut out wave and a piece of card.

CERN annonced today that it has discovered a new subatomic particle with a high confidence that it could be the uch sought after Higgs Boson.
This is the subatomic particle which gives objects mass.

Truly a momentous day for science. Congratulations to the scientists at CERN!

Salt Waves Movie 1

Salt Waves Movie 2

Hi physicists! Take a look at our salt waves we made today.

Watch Salt waves movie 1 and 2 and compare the speed which the poster paper was pulled along the bench.

The frequency of the swinging salt funnel stays the same in both movies.

What can you say about the wavelength of the salt waves as the speed of the poster is increased keeping the funnel frequency the same?

Study the equation on speed, distance and time. Use Bart`s hand to cover up what you are trying to find. Then press the forward arrow to try out some problems.

Click on the “Show me wavelengths” and “Show me amplitudes” to revise the buzzwords for waves.
Then click on the forward arrows to find out more about waves.

Hi new physicists! Here is a video of our experiment which we carried out last day.
