There’s not enough information to compare n₁ and  n₂

n₁ >  n₂

n₁ <  n₂

The new wire would vibrate and form a visible standing wave at the 1st harmonic (the fundamental frequency).

The new wire might vibrate but would not form a visible standing wave.

There is not enough information to make a reasonable prediction.

The new wire would vibrate and form a visible standing wave at the 3rd harmonic.

The new wire would vibrate and form a visible standing wave at the 4th harmonic.

The new wire would vibrate and form a visible standing wave at the 2nd harmonic (just like the previous wire).

The reading uncertainty on the function generator.

Propagating the uncertainty in the frequency from other variables such as: the tension in the wire, the linear mass density of the wire, the wavelength, and/or any other variables.

Overtones/higher harmonics occurring in the wire making it difficult to view the standing wave.

Deciding by eye if the frequency corresponds to a standing wave.

Between 0.01 m/s and 0.1 m/s

Between 1 m/s and 100 m/s

Between 100 m/s and 1 km/s

Between 0.1 m/s and 1 m/s

The positions of the standing waves which the wire undergoes average displacement during the oscillation. 

The positions of the standing waves which the wire undergoes maximum displacement during the oscillation. 

The positions of the standing waves which the wire undergoes minimum displacement during the oscillation. 

The positions of the standing waves which the wire undergoes no displacement during the oscillation.
