| How can you use an Oscilloscope and 2 Microphones to find the Wavelength of a Soundwave? | -First set the Oscilloscope up correctly so that you get 2 Waves for the Microscopes [Has a Separate Wave]
-Then, have the Microphones next to the Speaker, and slowly distance one away until the 2 Waves align each other, but has moved 1 Wavelength apart
-Measure the Distance between the Microphone to find the Wavelength
-Then, using whatever you put as the Frequency for the Signal Generator, you can find the Speed |
| How, using a Ripple Tank with a Signal Generator attached to the Dipper, can you find the Frequency? | -First, get a Cork and Stopwatch
-Then, make the Cork float in the Ripple Tank, and watch it Bob up and Down
-When the Cork is at the Top of a Bob, start the Stopwatch
-Record how many times the Cork Bobs in a given Time
-Then Divide that Number by how Long you were Timing for, to get the Bobs per Second, also known as the Frequency. |
| How, using a Ripple Tank with a Signal Generator attached to the Dipper, can you find the Wavelength? | -First, get a Strobe Light
-Then place a Card that's Covered with Centimetre-Squared Paper behind the Tank
-Turn on that Strobe Light, and change the Frequency until the Waves 'Freeze'
-Using the Squared Paper, measure the Distance that the Waves Cover, and then see how many Waves there is, and divide them Together to get an Average Wavelength |
| How, using a Ripple Tank with a Signal Generator attached to the Dipper, can you find the Wave Speed? | -First get a Pencil, A Friend and a Stopwatch
-Have a Large Piece of Paper next to the Tank
-As the Waves move across, have one of you Track the Path of one of the Crests on the Paper, using the Pencil
-The other Person should use the Stopwatch and Record how long you have been Drawing for.
-Get the Speed by getting the Length of the Line and putting it in this Formula: Distance = Speed x Time |
