Light at the double slit. How does this strange light pattern arise through the double slit? What does this have to do with diffraction and interference and how can you determine the path difference and the wavelength of the light from the light pattern? 00:00 Start 00:31 Phenomena at the double slit 01:50 Light as a wave 03:39 Diffraction and interference at the double slit 06:05 Path difference and determination of the wavelength 13:48 Cheat sheet https://www.leifiphysik.de/optik/beug... https://www.leifiphysik.de/optik/beug... https://www.leifiphysik.de/optik/beug... #Optics; #Diffraction; #Interference; #Double slit; #Lekkerwissen; #Cheat sheet
