No. Frequency and speed are completely unrelated concepts. How frequently something occurs is not the same as how quickly. In the universe, at least in the four dimensions that we can understand, there is a speed limit set by the speed of light.

<h3>What is Frequency?</h3>

The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasize differences with spatial and angular frequencies, respectively. In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time. The pace of direction changes in current per second is known as frequency. It is expressed in hertz (Hz), a unit of measurement that is used internationally. One hertz is equivalent to one cycle per second. A cycle is one whole alternating current wave.

You open a bank account and deposit $10. Every month you deposit $25 dollars. Let T represent the total money in your account af
Pavlova-9 [17]
The total money that will be present in the bank account, disregarding the percent rate of money increase is the sum of the initial deposit and the all the amounts deposited for m months, 25m. Thus, the answer should be,
                                    T = 10 + 25m

The speed of sound is 346m/s if a sound wave travels at a frequency of 55hz what would it’s wavelength be
algol [13]

Answer:

6.29 m

Explanation:

The speed of a wave is equal to frequency times wavelength, so to find wavelength you'd have to divide frequency by both sides, speed(346) divided frequency(55) = 6.29 m

I'm not so sure about this let me know if I'm wrong
