Wave Properties and Interactions Simulation

1. Amplitude → height
   Set wavelength = 4, offset = 0. Change amplitude from 1 → 0.5 → 0.
   

• 1. What visible change do you see in the crest/trough height at each setting?

• 2. When amplitude = 0, what does the graph look like?

2. Wavelength → spacing
   Keep amplitude = 1, offset = 0. Compare wavelength 2 vs 6.
   

• 1. Which one shows crests/troughs closer together?

• 2. Describe how the distance between two adjacent crests changes.

3. Offset → horizontal shift
   Keep two identical waves (same amplitude and wavelength). Set the second wave’s offset to +2.
   

• 1. How do the crests of the two waves line up before and after the offset change?

• 2. Describe what you see when you slide the offset slowly from 0 to +2.

4. Constructive interference (adding up)
   Use two waves with amplitude = 1, wavelength = 4, offset = 0 for both.
   

• 1. At a point where both single waves read +1, what value do you see on the combined wave?

• 2. Describe what the combined wave looks like when the crests overlap.

5. Destructive interference (canceling out)
   Set wave A amplitude = +1 and wave B amplitude = –1 (same wavelength and offset).
   

• 1. What happens to the combined wave where a crest from A meets a trough from B?

• 2. Write one sentence describing the overall look of the combined wave.
