Question

If a wave has a speed of 47 m/s and a wavelength of 25 m, what is the frequency of the wave? Give your answer to 2 decimal places.

Answer 1

The formula is:

v = f λ

Where,

v is the velocity or speed of the wave (in m/s)

f is the frequency of the wave (in Hz)

λ is the wavelength of the wave (in m)

We can rearrange this formula to solve for the frequency:

f = v / λ

We are given the speed and the wavelength of the wave, so we can plug them into the formula:

f = 47 m/s / 25 m

f = 1.88 Hz

To give the answer to 2 decimal places, we round it to:

f = 1.88 Hz

Therefore, the frequency of the wave is 1.88 Hz.

Step-by-step explanation:

Answer 2

1.88 Hz.

Step-by-step explanation:

The frequency (f) of a wave is related to its speed (v) and wavelength (λ) by the equation f = v/λ.

So to find the frequency of a wave with a speed of 47 m/s and a wavelength of 25 m, we just need to substitute these values into the equation:

f = 47 m/s / 25 m

f = 1.88 Hz

Rounding to 2 decimal places, the frequency of the wave is 1.88 Hz.
