String Vibrations: Determine Wavelength & Fundamental Frequency

[Husker70]

Homework Statement

A standing wave is established in a 120-cm-long string fixed at both
ends. The string vibrates in four segments when driven at 120Hz.
(a) Determine the wavelength
(b) What is the fundamental frequency of the string?

Homework Equations

(a) Lambda = 2L/n

The Attempt at a Solution

(a) Lambda = 2(120cm) / 4 = 60cm

Is this right? doesn't seem to be
