Unformatted text preview: Experimental Question 2 Diffraction and Scattering of Laser Light The aim of this experiment is to demonstrate and quantify to some extent the reflection, diffraction, and scattering of light, using visible radiation from a Laser Diode source. A metal ruler is employed as a diffraction grating, and a perspex tank, containing water and diluted milk, is used to determine reflection and scattering phenomena. Section 1 (6 marks) Place the 150 mm length metal ruler provided so that it is nearly normal to the incident laser beam, and so that the laserr beam illuminates several rulings on it. Observe a number of spots of light on the white paper screen provided, caused by the phenomenon of diffraction. Draw the overall geometry you have employed and measure the position and separation of these spots with the screen at a distance of approximately 1.5 metres from the ruler. Using the relation N = h sin where N is the order of diffraction is the radiation wavelength h is the grating period...
