    Answer:

    4.91 x 10⁻⁷ m

    Explanation:

    the applicable formula is

    v = fλ

    where

    v = velocity (i.e speed) = given as 3.0 x 10⁸ m/s

    f = frequency = given asw 6.11 x 10¹⁴

    λ = wavelength

    if we rearrange the equation and substitute the values given above,

    v = fλ

    λ = v/f  

    = 3.0 x 10⁸ / 6.11 x 10¹⁴

    = 4.91 x 10⁻⁷ m
