    Answer:

    71 × 10^ -9 meters

    Explanation:

    From wave equation

    Velocity = frequency × wavelength

    Velocity of electronic radiation = 3× 10^8

    Making the wavelength as the subject of formula, we have

    Wavelength = Velocity / frequency

    = 3×10^8 /4.21 × 10 ^15

    0.71 × 10^-7

    In nanometers

    We have 0.71 ×10^2 × 10 ^-9

    = 71 nanometers
