As your hand moves back and forth to generate longitudinal pulses in a spiral spring, your hand completes 2.4 back-and-forth cycles every 6.54 s. The velocity of the pulse in the spring is 0.832 cm/s. What is the wavelength? Answer in units of m.

Wavelength;λ = 0.0227 m

Explanation:

We are given that;

Velocity; v = 0.832 cm/s = 0.00832 m/s

f = 2.4 revs / 6.54 s = 0.367 hz

Now, wavelength is given by the formula;

Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency.

Wavelength usually is expressed in units of meters. The symbol for wavelength is λ,

so λ = v/f

λ = 0.00832/0.367 = 0.0227 m
