Observe Simulation: Assignment2
This is frequency generator app. Also you can adjust amplitude of wave Which results in Amplification of Sound. Make sure to keep the Volume low and if possible use earphones not speakers.
Steps to Use the above Applet. AIM: We want to observe the effect on how we perceive sound (pitch) of different frequency and amplitude.
Q 1
What do you think changes in Waveform when you incraese green & pink sliders from left to right ( the blue color line that changes its form when slider position is changed) What quantity changes when the waveform expands vertically. Which color slider will you use to expand the width of waveform.
Q2.
As you can see in the applet there is kind of graph in background. If you observe more closely there you will see X & Y axis . X being the horizontal darker line in middle with numbers & Y being the Vertical darker line towards left end of applet screen. Can you give out names of what might be plotted in as quantities in applet on X & Y axis.
Q3
Which slider will you use to compress (squeeze) or expand the waveform . Where should you move the slider . Note: Observe the effects of both slider on sound and blue zig zag waveform.
