Human: Diffraction at the Grid (Transmissions and Reflection Grid) in a Student Experiment. Low-Cost Student Experiment. All parts are fixed to a steel plate using a magnet. A CD serves as a reflection grid, while the transmission grid is available for approximately 1 euro per piece in various online stores. The laser box and lid require: 4 x M3x10 cylinder screws with internal hexagon 4 x low-profile square nuts (M3) 2 x banana sockets, such as Reichelt BIL 20 BL and BIL 20 RT 1 x round wiper switch, 20.2 mm mounting size, such as Reichelt WS R13-112 AAAA 1 x Class 1 laser module, such as Reichelt PICO 70125658 1 x disc magnet, 25mm diameter, 5mm height, such as supermagnete FE-S-25-05 A quartered DIN-A4 sheet fits on the screen. Alternatively, it can be printed in white. The paper has the advantage that students can mark and measure the maxima with a pencil later. The grid holder accommodates diar frames, like those available in many physics collections. For the grid holder, CD holder, and screen, the corresponding number of disc magnets are required. With magnet cover, the magnet can be fixed.
