Answer:
Electromagnetic waves transfer energy through vibrations of electric and in magnetic fields. For sound waves the energy is transferred through the vibration of air particles or particles of a solid. Waves also carry energy, the amount of energy they carry depends on their frequency and their amplitude. The more energy and the higher frequency amplitude, the more energy waves are ^‿^
I'll say net force because if you search up the meanings of them net force makes much more sense.
Generally, the definition of the speed is the distance per the time unit
Then, for one complete wave, the wave moves a distance equal to the wavelength (λ) in time equal to the period (T)
λ/T
but we now that the frequency (f) is equal to the reverse of the period (T)
Then the speed of the wave is determined by
λ f
in our problem, we need to find the <u>wavelength</u>
<em>note that:</em><u><em> the speed must be in m/s not km/s , that you need to convert km to m by multiplyling by 1000</em></u>
λ =
