How do the properties of an electromagnetic wave change as a result of increasing the period of the wave?
astra-53 [7]

Answer:

as the period decreases, the frequency and energy of the wave increase

Explanation:

Electromagnetic waves are oscillations of the electric and magnetic fields, described by maxwell's equations, the speed of the wave is called the speed of light

            c = λ f

            E = E cos (kx - wt)

Angular velocity is related to frequency and period.

           w = 2π f = 2π / T

Let's analyze what happens when the wave period decreases, angular velocity and frequency increase.

This increase in frequency is reflected with the Planck equation in wave energy

                E = h f

Therefore the wave carries more energy and can lead to stronger interactions with matter.

In summary, as the period decreases, the frequency and energy of the wave increase
