A laser beam is incident on a 600 lines per millimeter diffraction grating. The wavelength of the light produced by the laser is 630 nm and the interference pattern is observed on a screen 2.00 m from the grating. Determine
a) angular deflection of the first-order bright fringe,
b) angulardeflectionofthesecond-orderbrightfringe,
c) the maximum number of bright fringes that can be observed.
