3. Additional information [total 1.0 pts] : no.1 no.3 no.2 Distance of the grating (no.1) Distance of the grating (no.2) to the left wall is practically zero to the right wall is practically zero [ 0.2 pts ] [ 0.2 pts ] Lines of grating no.1 is at Lines of grating no. 2 right angle to the slit is parallel to the slit [ 0.3 pts ] [ 0.3 pts ]

4. Diffraction grating [total 2.0 pts] : drawing and labels should be complete d [ 0.6 pts ] θ θ Path length difference: = d sin θ , d = spacing of the grating Diffraction order: = m λ , m = order number Hence, for the first order ( m = 1): sin θ = λ / d [ 0.4 pts ] Observation data: tan θ θ sin θ 0.34 18.78 0 0.3219 0.32 17.74 0 0.3048
