This multimedia tutorial provides explanations and models of wave diffraction. It contains multiple images, animations, and interactive simulations designed to represent what happens when a wave encounters an obstacle. The tutorial begins by explaining how the amount of diffraction depends on the wavelength and the size of the object being encountered. It progresses to discussions of various diffraction effects, Huygen's Principle, and concludes with diffraction through two slits (a simulation of Young's classic experiment). Excellent resource for teachers who wish to build content knowledge on the topic. This item is part of a larger collection of multimedia tutorials on waves and acoustics, developed by the University of Salford, UK. The tutorials are accompanied by more than 60 high-speed videos and animations that represent fundamental properties of waves.
