v=fλ

The Attempt at a Solution



f= cycles/time
f= 45/60
f= 0.75 Hz

The trouble I am having is wondering if λ is 28 m or do i have to do something else to find λ?

No, the wavelength itself is not 28, but 28 is a factor of wavelength. One wavelength is the distance from crest to crest, or trough to trough, or however you want to see it. It is however long the wave is until it repeats itself.

Related to Water Waves - Universal Wave Equation

1. What is the Universal Wave Equation for water waves?

The Universal Wave Equation for water waves is a mathematical formula that describes the behavior of waves on the surface of a body of water. It is expressed as: c = √(gλ/2π), where c is the speed of the wave, g is the acceleration due to gravity, and λ is the wavelength of the wave.

2. How is the Universal Wave Equation derived?

The Universal Wave Equation is derived from the basic principles of wave mechanics, such as the conservation of energy and the relationship between wave speed, wavelength, and frequency. It is also based on the assumption that waves on the surface of water are sinusoidal in nature.

3. What does the Universal Wave Equation tell us about water waves?

The Universal Wave Equation tells us the speed at which a water wave will travel, given its wavelength and the acceleration due to gravity. It also shows us that the speed of a wave is directly proportional to its wavelength, and inversely proportional to the square root of the acceleration due to gravity.

4. Can the Universal Wave Equation be applied to all types of water waves?

Yes, the Universal Wave Equation can be applied to all types of water waves, including ocean waves, wind waves, and even small ripples on a pond. However, it is important to note that other factors, such as wind speed and water depth, can also affect the behavior of water waves.

5. How is the Universal Wave Equation useful to scientists and engineers?

The Universal Wave Equation is a fundamental equation that helps scientists and engineers understand and predict the behavior of water waves. It is used in a variety of fields, such as oceanography, coastal engineering, and marine science, to study and model the effects of waves on coastlines, structures, and marine ecosystems.
