    Answer:

    7.86×10⁻⁷ m

    Explanation:

    Using,

    v = λf……………… Equation 1

    Where v = velocity of electromagnetic wave, λ = wave length, f = frequency.

    make λ the subject of the equation

    λ = v/f…………… Equation 2

    Note: All electromagnetic  wave have the same speed which is 3×10⁸ m/s.

    Given: f = 3.818×10¹⁴ Hz

    Constant: v = 3×10⁸ m/s

    Substitute these values into equation 2

    λ  =  3×10⁸/3.818×10¹⁴

    λ  = 7.86×10⁻⁷ m

    Hence the wavelength of the electromagnetic radiation is  7.86×10⁻⁷ m
