What Wavelengths Create Standing Waves on a 2.0 Meter Stretched String?

Homework Statement

A stretched string fixed at both ends is 2.0 meters long. What are three wavelengths that will produce waves on this string. Name at least one wavelength that would NOT produce a standing wave pattern.

Homework Equations

The Attempt at a Solution

Since standing waves have whole number amounts of half lengths I said that wavelengths of 2.0 meters, 1.0 meters and 0.5 meters would all work and said 1.79 meters would not because it is not even division based on whole numbers of half wavelengths.

Is this right or is there more to this?
