Answer
To find the number of crests, we observe the diagram and identify the visible crests between points P and Q. In this case, there are 12 distinct crests.
Step 2
The distance between P and Q is 42 cm. Calculate the wavelength of the water wave in Figure 3.

Answer
To calculate the wavelength, we use the formula:
ext{Wavelength} = rac{ ext{Distance between P and Q}}{ ext{Number of crests}}
