When i wave a charged golf tube at the front of the classroom with a frequency of two oscillations per second, i produce an electromagnetic wave of frequency 2hz. what is the wavelength of this wave?

To solve the exercise it is necessary to take into account the concepts of wavelength as a function of speed.

From the definition we know that the wavelength is described under the equation,

Where,

c = Speed of light (vacuum)

f = frequency

Our values are,

Replacing we have,

Therefore the wavelength of this wave is
