Light of Wavelength $\lambda$ Is Normally Incident on a Diffraction Grating G

Question 5

Multiple Choice

Light of wavelength $\lambda$ is normally incident on a diffraction grating G. On the screen S, the central line is at P and the first order line is at Q, as shown. The distance between adjacent slits in the grating is: $Light of wavelength \lambda is normally incident on a diffraction grating G.
