How far apart is this bright band from the central peak

Reference no: EM13667188

Two slits are illumined by a 621nm light. The angle among the zeros-order bright band at the center of the screen and the fourth-order bright band is 15.9^o. If the screen is 133 cm from the double slit, how far apart is this bright band from the central peak?
