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.
