8.3b Ex4 MJ17 P23 Q5 Diffraction Grating Graph | AS Superposition | Cambridge A Level 9702 Physics

Ex4 - 9702/23/M/J/17: (a) A diffraction grating is used to determine the wavelength of light. (i) Describe the diffraction of light at a diffraction grating (ii) By reference to interference, explain 1. the zero order maximum, 2. the first order maximum (b) A diffraction grating is used with different wavelengths of light. The angle θ of the second order maximum is measured for each wavelength. The variation with wavelength λ of sin θ is shown in Fig. 5.1. (i) Determine the gradient of the line shown in Fig. 5.1. (ii) Use the gradient determined in (i) to calculate the slit separation d of the diffraction grating. (iii) On Fig. 5.1, sketch a line to show the results that would be obtained for the first order maxima. #9702s17p23 #ASdiffractionGratingP2 #ASphysicsGraphsP2 #Lv2 AS #Superposition Playlist:    • Ch8 Superposition | CAIE 9702 AS Physics   AS #Waves Playlist:    • Ch7 Waves | CAIE 9702 AS Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
