Pls help me its due in 20 minutes.

  11. 1, 4.5

  12. right; 4.5 > 1

  13. 10, 3

  14. left; 10 > 3

Explanation:

All you're being asked to do is count the squares in the pictures.

11. The number of squares for the left wave from bottom to top is 2, so the amplitude is 1/2 that, 2/2 = 1. For the right wave it is 9 squares from bottom to top, so the amplitude is 9/2 = 4.5.

  left amplitude: 1, right amplitude: 4.5

__

12. The right wave has greater amplitude. Evidence: 4.5 > 1. It also takes up more vertical space in the picture.

__

13. It is difficult to determine the wavelength of the left wave, because two full peaks are not shown. If we try to match corresponding points, they appear to be about 10 squares apart.

The right wave has 2 peaks in 6 squares, so about 3 squares between peaks.

  left: wavelength 10, right: wavelength 3

__

14. The left wave has greater wavelength. Evidence: 10 > 3.
