Select the best definition for wavelength. the height of an oscillating electromagnetic wave the rate at which electromagnetic waves oscillate. the distance between two crests of an electromagnetic wave. the oscillations of electric and magnetic fields select the best definition for frequency. the oscillations of electric and magnetic fields. the height of an oscillating electromagnetic wave. the distance between two crests of an electromagnetic wave. the rate at which electromagnetic waves oscillate

Wavelength: the distance between two crests of an electromagnetic wave

Frequency: the rate at which electromagnetic waves oscillate

Explanation:

For a transverse wave (such as the electromagnetic waves), we can define the following quantities:

Wavelength: it corresponds to the distance between two consecutive crests (or between two consecutive troughs) of the wave

Frequency: the number of complete oscillations of the wave per unit time

Period: it is the time it takes for the wave to complete one oscillation - it is equal to the reciprocal of the frequency

Amplitude: it is the maximum displacement of the wave, measured with respect to its equilibrium position

this a false
