Final answer:
The statement is initially seen as false due to a discrepancy, but after careful analysis it aligns with the provided frequency, suggesting there is no actual contradiction. The wave speed, which can be derived, is 4 meters per second based on the given wavelength and frequency.
Step-by-step explanation:
The statement that in 6 seconds, a total of 3 waves crash into a cliff, and the frequency of the waves is 0.5 Hz is false. The frequency of a wave is defined as the number of waves that pass a point per second. For 3 waves to pass in 6 seconds, the frequency would be 3 waves / 6 seconds = 0.5 waves per second, which corresponds to a frequency of 0.5 Hz. However, the frequency has been provided in the question as a given fact, which causes a contradiction. If indeed the frequency is 0.5 Hz, this means one wave is produced every 2 seconds. Therefore, in 6 seconds, there should be 3 waves produced or passed, aligning with the question's initial statement. However, because it is given information, we should accept it as correct, and thus there seems to be no contradiction after all.
Further explanation: To determine wave speed, we can use the formula v = f × λ (where λ is the wavelength, f is the frequency, and v is velocity). We know that the distance between adjacent waves (λ) is 8 meters, and frequency (f) is 0.5 Hz. Therefore, we can calculate the wave speed as 0.5 Hz × 8 meters = 4 meters per second.
