Below are some problems based on wavelength which may be helpful for you.

A harmonic wave is traveling along a rope. The source generating the waves completes 50 to and fro motions in 25 s. A trough travels 2m in 4s. calculate the wavelength of the wave?

Time taken for 50 oscillations = 25 s

Time for 1 oscillation, t = $\frac{25}{50}$ = 0.5 s

Frequency of 1 oscillation, f = $\frac{1}{0.5}$ = 2 Hz

The wave travels a distance of 2m in 4s. The wave speed is given by v = $\frac{2}{4}$ = 0.5 ms

The wavelength is given by $\lambda$ = $\frac{v}{f}$

= $\frac{0.5}{2}$

= 0.25 m.

Frequency f = 256 Hz,

Distance d = 25 m,

No of vibrations/ oscillations = 20

Wavelength $\lambda$ = $\frac{Distance}{No of oscillations}$

= $\frac{25}{20}$

= 1.25 ms
