Wave Number given Wavelength, Wave Period and Water Depth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wave Number for Water Wave = (atanh((Wavelength*Wave Angular Frequency)/([g]*Wave Period)))/Water Depth
k = (atanh((L*ω)/([g]*T)))/d
This formula uses 1 Constants, 2 Functions, 5 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Functions Used

tanh - The hyperbolic tangent function (tanh) is a function that is defined as the ratio of the hyperbolic sine function (sinh) to the hyperbolic cosine function (cosh)., tanh(Number)
atanh - The inverse hyperbolic tangent function returns the value whose hyperbolic tangent is a number., atanh(Number)

Variables Used

Wave Number for Water Wave - The Wave Number for Water Waves quantifies the number of waves per unit length along the surface of the water.
Wavelength - (Measured in Meter) - Wavelength is the distance between successive crests, troughs, or any corresponding points on a wave.
Wave Angular Frequency - (Measured in Radian per Second) - Wave Angular Frequency is the rate of change of the phase of the wave over time, given by the symbol ω (omega).
Wave Period - (Measured in Second) - Wave Period is the time it takes for successive wave crests or troughs to pass a fixed point.
Water Depth - (Measured in Meter) - Water Depth of the considered catchment is the depth as measured from the water level to the bottom of the considered water body.

STEP 1: Convert Input(s) to Base Unit

Wavelength: 0.4 Meter --> 0.4 Meter No Conversion Required
Wave Angular Frequency: 6.2 Radian per Second --> 6.2 Radian per Second No Conversion Required
Wave Period: 0.622 Second --> 0.622 Second No Conversion Required
Water Depth: 2.15 Meter --> 2.15 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k = (atanh((L*ω)/([g]*T)))/d --> (atanh((0.4*6.2)/([g]*0.622)))/2.15

Evaluating ... ...

k = 0.200698139739852

STEP 3: Convert Result to Output's Unit

0.200698139739852 --> No Conversion Required

FINAL ANSWER

0.200698139739852 ≈ 0.200698 <-- Wave Number for Water Wave

What is Wave Number?

Wave Number is the spatial frequency of a wave in a given medium, typically measured in reciprocal units of distance, such as radians per meter or cycles per meter.

What is Time period of a Wave?

The time taken for one complete oscillation in the density of the medium is called the time period of the wave. It can also be defined as the time taken by two consecutive compressions (Trough) or rarefactions (Crest) to cross a fixed point. It is represented by the symbol T.
