    Answer:

    a) d= 0.0002cm

    b) m=3

    Explanation:

    From the question we are told that:

    Width of diffraction grating W_g= 5cm

    Width of silt w_s 0.0001 cm

    Distance d= 0.0002cm

    a)

    Generally the grafting element is the distance b/w  the silts

    d= 0.0002cm

    Therefore the grafting element is

    d= 0.0002cm

    b)

    Generally the equation for diffraction state is mathematically given by

     dsin\theta=m\lambda

    Since

     sin\theta \leq 1

    Therefore

     m \leq \frac{d}{\lambda}

     m \leq \frac{0.0002}{0.000055}

     m \leq 3.6

    Therefore orders observed with \lambda is

     m=3
