    Answer:

    d = 0.124 mm

    Explanation:

    It is given that,

    Wavelength of light is 525 nm

    It makes second maximum at an angle of 0.482 degrees

    We need to find the separation of the slits.

    For 2nd maximum, the equation for double slip experiment is given by :

    d\sin\theta=n\lambda

    d = separation of the slits

    d=\dfrac{n\lambda}{\sin\theta}\\\\d=\dfrac{2\times 525\times 10^{-9}}{\sin(0.482)}\\\\d=0.124\ mm

    So, the separation of the slits is 0.124 mm.
