    Answer:

    Option D.) 5.0 x 10^-4m

    Explanation:

    Data obtained from the question include:

    f (frequency) = 6 x 10^11 Hz

    v (velocity) = 3.00 x 10^8 m/s

    λ (wavelength) =?

    Using the equation v = λf, the wavelength can be obtained as illustrated below:

    v = λf

    λ = v/f

    λ = 3.00 x 10^8/6 x 10^11

    λ = 5 x 10^-4m

    Therefore, the wavelength of the beam of the electromagnetic radiation is 5 x 10^-4m
