2. The amplitude of wave 1 is 2.8 y-axis blocks.
3. The amplitude of wave 2 is 2 y-axis blocks.
4. The wavelength of wave 1 is 4 x-axis blocks.
5. The wavelength of wave 2 is 2 x-axis blocks.
6. You drew 1 wavelength of wave 1.
7. You drew 2 wavelengths of wave 2.
8a. The completed table is:
x-axis (blocks) | Height of wave 1 (y-axis blocks) | Height of wave 2 (y-axis blocks) | Height of wave 1 + wave 2 (y-axis blocks)
0 | 0 | 0 | 0
1 | 0.8 | 2 | 2.8
2 | 1.5 | 0 | 1.5
3 | 2.2 | -2 | 0.2
4 | 2.8 | 0 | 2.8
9. The resulting wave from adding the two original waves shows a pattern where the peaks and troughs of the combined wave are determined by the algebraic sum of the displacements of the individual waves at each point, demonstrating both constructive interference (where waves add to create larger amplitudes) and destructive interference (where waves partially or fully cancel each other).
