D)the order of the line
E)the index of refraction

Question

Quizplus · Accepted Answer

According to the equation, d is the slit separation. The other parameters in the equation include m (order of the line), θ (angle of diffraction), and λ (wavelength of the incident light). Therefore, choice C, the slit separation, is the best choice.
