    Answer:

    4.13×10⁻⁷ m

    Explanation:

    Applying

    v = λf………………. Equation 1

    Wherfe v = speed of light, λ = wavelength of light, f = frequency of light.

    make λ the subject of the equation

    λ = v/f………………….. Equation 2

    Note: Light is an electromagnetic wave, and all electromagnetic wave moves with thesame speed which is 3×10⁸ m/s.

    From the question,

    Given: f = 7.26×10¹⁴ Hz

    Constant: v = 3×10⁸ m/s

    Substitute these values into equation 2

    λ = (3×10⁸)/(7.26×10¹⁴)

    λ = 4.13×10⁻⁷ m
