Find the distance between the two spectrum lines

Reference no: EM13546164

Light of two wavelengths, ? = 520 nm and ?' = 550 nm falls normally on a diffraction grating having 3500 lines/cm. The emergent light is observed on a screen 1.50 m from the plane of the grating. Determine the distance between the two spectrum lines in the first order. Repeat for the second order.
