Light is incident on a grating at an angle t/J as shown in
Chapter 36, Problem 81(choose chapter or problem)
Light is incident on a grating at an angle t/J as shown in Fig. 36-49. Show that bright fringes occur at angles 8 that satisfy the equation d(sin t/J + sin 8) = rnA, for rn = 0,1,2, .... (Compare this equation with Eq. 36-25.) Only the special case t/J = o has been treated in this chapter. ~Grating Fig. 36-49 81.
