IB PHYSICS UNIT 11 RESOLUTION1.(a) Using the axes below draw a graph to show how the intensity of the pattern varies with distance along the screen forsingle slit diffraction. The point X on the screen is shown as a reference point.(This is a sketch graph; you do not need toadd any numerical values.)(3)X(b)In this experiment, the light from point source P has a wavelength of 500 nm and the width of the central maximum of intensity on the screen is 10.0 mm. When light of unknown wavelength   is used, the width of the central maximum of intensity is 13.0 mm. Determine the value of  .(2)Another point source Q, emitting light of the same wavelength as P (500 nm) is placed 5.0 mm from P and the two sourcesare arranged as shown below.The distance between the sources and the slit is 1.50 m.(c)(i)State the condition for the image of P and the image of Q formed on the screen to be just resolved.(ii)Determine the minimum widthbof the slit for the two images to be just resolved.2.λλ
