During an experiment, a researcher uses a wave generator to produce waves in a pool of water. He determines the frequency, wavelength, and speed of the waves before changing the frequency to study its effect on the wavelength and speed of the waves. The researcher records his observations, as shown. The researcher observes the new reading and concludes that as the frequency increases, the wavelength decreases, but the speed always remains the same. Is the conclusion formed by the researcher valid?

• No. The researcher must repeat the experiment with only the same values to verify the data.

• Yes. The researcher recorded the values for two different frequencies, which is enough to confirm a pattern.

• Yes. The researcher recorded the values for two different speeds, which is enough to confirm a pattern.

• No. The researcher must repeat the experiment with both the same values and additional values to verify the data.
