    The answer is 735 Nanometer

    Explanation:

    Solution to this problem

    Given that:

    Solution)

    The Redshift is categorized by the difference related between wavelength (emitted) and wavelength (observer).

    Now,

    The wavelength can be computed as:

    1+z=/lambda (observer) / div / lambda (emitted)

    hence,

    1 + 0.05 = λ (observer) / 700 nm

    Gives

    = 1.05*700 = 735 nm

    Therefore, The wavelength from that source for an observer would be 735 nanometer
