Discuss the importance of frequency, wavelength and energy in the study of electromagnetic wave? Would this determine how
safe are the electromagnetic waves? explain.

The importance of frequency, wavelength and energy in the study of electromagnetic wave has been explained below.

Formula for energy in electromagnetic waves is given by;

E = hf

E = hfOr E = h(c/λ)

Where;

h is Planck's constant

f is frequency

c is speed of light

λ is wavelength

From the above, we see that;

The energy of an electromagnetic wave is directly proportional to the frequency and inversely proportional to its wavelength.

Similarly, shorter wavelengths will produce more energy radiated and longer wavelengths produces lesser energy.

   c = λf

E = h f

the characterization of electromagnetism is given as a function of energy or frequency.

Explanation:

In waves the frequency and donut length are related by the speed of the wave

        c = λf

therefore the two quantities are not independent.

The energy of an electromagnetic wave is given by

        E = h f

where h is the planck constant and f the frequency of the wave

This energy determines how the wave interacts with the surrounding medium. Low energy waves only create movement of the atomic nuclei and as the energy increases, the electrons are excited.

As a result of the above, the characterization of electromagnetism is given as a function of energy or frequency.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
