Which of these waves has the greatest frequency? Question 46 options:

Wave having a length of 9 meters and a height of 6 meters.

Wave having a length of 20 meters and a height of .5 meters.

Wave having a length of 10 meters and a height of 1.5 meters.

Wave having a length of 14 meters and a height of 4 meters.

Wave having a length of 9 meters and a height of 6 meters.

Explanation:

Assuming that this is a sound wave or an electromagnetic wave, we know that those have a constant speed.

The speed of sound and speed of light are the same for any sound or electromagnetic wave respectively.

And we also have the equation:

v = λ*f

Where:

v = velocity

f = frequency

λ = wavelength

And because v is a constant, we can write:

f = v/λ

Now the wavelength is in the denominator, then the wave with the smaller wavelength will be the one with a larger frequency.

The option with the smallest wavelength is

Wave having a length of 9 meters and a height of 6 meters.

Notice that the height of the waves is also given, this is actually related to the intensity of the wave, so that information does not affect this particular question.
