Question

In the case of mechanical waves, what causes or determines the speed of the waves, the frequency of the waves, and the wavelengths of the waves?

Answer 1

Answer:

The medium determines the speed of the wave, the wavelength and frequency.

Explanation:For different media the speed of the wave will variate, because each media have different properties. The following equation makes a relation between the speed of the wave, the wavelength and the frequency:

$v = \lambda.\nu$ (1)

Where v is the speed of the wave, \lambda is the wavelength and \nu is the frequency

Equation 1 shows that the speed of the wave is directly proportional to the product of the wavelength and the frequency. If the speed is lower the wavelength will decrease but the frequency increase, as is shown in equation 2:

$\lambda = \frac{v}{\nu}$   (2)

Equation 1 can be rewritten for the case of the frequency:

$\nu = \frac{v}{\lambda}$     (3)

So, according with equation 3, if the speed is higher the frequency will increase but the wavelength will decrease (inversely proportional).

Answer 2

The rate in witch ditermans the speed or vibration of the movment under the waves witch couses vibrational freequencys to be disrupted.
