The Wave Equation

Posted by Mr Mallon on September 25, 2012

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.

Paper Card Wave Machine

Posted by Mr Mallon on September 4, 2012

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.

Salty Wave Machine

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?
