Multiple Slit & Grid Diffraction Intensity by Phywe

Laser light is shone on multiple slits, all identical in width and spacing, and transmission grids with varying grid constants. The resulting diffraction patterns' positions and intensities are measured using a shiftable photo diode.

• Calculate Slit Width: Locate the first intensity minimum caused by a single slit and use this value to determine the slit's width
• Slit Intensity Distribution: Investigate the intensity patterns of diffraction from three, four, or even five slits, all of equal width and distance, and analyze the central peak intensity ratios
• Grid Diffraction Analysis: Identify the peak positions of various diffraction orders for transmission grids with different lattice constants, and use these to calculate the laser light's wavelength
