Of the three waves shown, Wave 2 has the greatest wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves

D. frequency, because there are more crests in the same length of rope than there are in the other waves

Explanation:

Wave frequency is defined as the number of waves passing a fixed point at a given time.

Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.

Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.

Hence, the correct answer is "D".
