6. Light is incident on a diffraction grating with 7600 lines/cm and the pattern is viewed on a screen 2.5 m from the grating. The incident light beam consists of two wavelengths 21 = 4.4 x 107 m and 22 = 6.8 x 107 m. Calculate the linear distance between the first -order bright fringes of these two wavelengths on the screen.
