Which of the following best describes the relationship between frequency and wavelength of electromagnetic waves?
Anna71 [15]

Answer:

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

Explanation:

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

Frequency, \, f = \dfrac{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.
