Wave Characteristics

Concept: Wave motion is described by the relation between wave speed, wavelength, and frequency: where = wave speed, = frequency, = wavelength. The wavelength is the distance between two successive crests or troughs of a wave.

Step 1: Determine the number of wavelengths.
If there are 11 consecutive crests, the number of intervals between them is one less than the number of crests. Thus,

Step 2: Calculate the wavelength.


Step 3: Use the wave speed formula.


Step 4: Substitute the given values.


Step 5: Final result.
