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.
How can we find a relationship between the length of a boomwhacker and the frequency of the sound it will produce?
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.
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.
Hi physics lovers here is your nasty nine health test you got today with answers.
Look over the questions and check the answers.
