A grating is made with 600 slits per millimeter. What is the slit separation? A) 600 nm B) 1.67 × 10^-6 m C) 3.33 × 10^-6 m D) 160 pm E) 916 nm

Question

Quizplus · Accepted Answer

The slit separation can be calculated using the formula d = 1/N, where N is the number of slits per unit length (in this case, per millimeter). Therefore, d = 1/600 mm = 1.67 × 10^-6 m, which is answer choice B.
