Answer
The type of wave is transverse. This is because in transverse waves, the oscillations are perpendicular to the direction of energy transfer, which is characteristic of water waves.

Answer
At point X, the water moves up and down. This movement is indicative of the oscillation pattern typical in water waves.

Answer
To calculate the wave speed, we use the formula:
v=f×λ
Substituting the values:
Frequency (f) = 2.0 Hz
Wavelength (λ) = 0.032 m
Calculating:
v=2.0×0.032=0.064 m/s
Thus, the wave speed is 0.064 m/s.

Answer
The wave with the longest wavelength is D. This can be determined visually from Figure 2, where wave D has the greatest distance between consecutive peaks.
