a
b
If the frequency remains constant, the wavelength increases.
The wavelength decreases as the frequency decreases.
The frequency increases as the wavelength decreases.
If the wavelength remains constant, the frequency increases.
С
d

Answer 1

The option that best describes the relationship between frequency and wavelength of electromagnetic waves is the third option

c. The frequency increases as the wavelength decreases

Step-by-step explanation:

The frequency of an electromagnetic wave, 'f', is given by the following formula;

`Frequency, \, f = (Wave \ Speed,v )/(Wavelength, \ \lambda)`

From the above formula, the frequency of an electromagnetic wave is inversely proportional to the wavelength, and therefore, a higher frequency, ('f', to increase), requires a lower wavelength, (λ, decreases)

The correct option is that the frequency of an electromagnetic increases as the wavelength of the wave decrease.
