    Sound in an Open Vertical Tube partially filled with Water

    I think this is correct. Please verify. a L = (2n-1)w/4 so w = 4L/13 w = 4(191.75)/13 = 59 cm b 59cm is .59m f = v/w = 343/.59 = appox 581.36 Hz c L =(2*8-1)*59/4 = 15*59/4 = 221.25cm.

    Waves on a String Fixed at the Ends

    I made a video to show what I did. I didn't worry about the right side. I figured it would be a mirror image flipped, as shown in every answer choice. I have no idea if I did it correctly.

    Waves on a String Fixed at the Ends

    Yes, I did it graphically - took each point, moved it 3 units right or, if it hit 5, the number of units left that remained. When I had done all points, I added the waves (or subtracted, as the case may be.) I only focused on the left side, as the right would be a mirror image. The video...

    Waves on a String Fixed at the Ends

    I tried drawing the wave, counting 3 meters (speed is 1 meter/s) and bounced back from the stationary point (at 5) when necessary. Using this, I found the answer to be drawing 2. Wondering if that's correct.
