Part A On the Sound tab, investigate briefly all the phenomena you explored with water waves above and describe any similarities in your results for sound. Specifically, describe
• wave pattern as seen on the screen
• shape and amplitude of the graph
• effect of frequency on wavelength
• effect of frequency on velocity
• pattern with two sources
•wave pattern with a single-slit barrier​
