What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m

Here is your answer

Frequency= 300 Hz

REASON:

We know that,

Velocity= frequency × wavelength

Here,

Velocity= 120 m/s

and, wavelength= 0.40 m

So,

frequency= velocity/wavelength

f= 120/0.40

f= 300 Hz

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
