Answer:
The correct opcion is C) inverse; more
Explanation:
Electromagnetic radiation is a combination of electric and magnetic fields that propagate through space carrying energy from one place to another.
Electromagnetic radiation can be described as a wave that is characterized by three fundamental parameters:
-
Wavelength (λ): It is the distance between the crests of two consecutive waves, and is measured in units of length (m). The amplitude of the wave depends on the radiant power of the emitting source.
- Frequency (ν or f): The number of times a wave oscillates in a second and is measured in cycles / second or hertz (Hz).
- Energy (E): The energy transported by electromagnetic radiation can be measured in Joules (J) or electron volts (eV).
The wavelength (λ) and frequency (f) of electromagnetic waves are related by the expression:
λ • f = c
where, c is the speed of light, λ is the wavelength of the light and f is the frequency.
Therefore, observing this expression, you will see that there is an inverse relationship between wavelength and frequency. The speed of light is constant in a given medium, so with an increase in frequency, the wavelength must decrease.
On the other hand, the frequency is directly proportional to the energy that carries a radiation, according to the equation:
E = h.f
where h is the Planck constant = 6.63 · 10-34 J / s.
Looking at this expression, you will see that the relationship between energy and frequency is direct, this means that when the frequency increases, the energy increases.
