Advanced Placement. Diffraction and Interference. Diffraction Light is a transverse electromagnetic wave.
Diffraction, and interference are phenomena observed with all waves. The light spreads around the edges of the obstacle. AS A Level Physics Revision. Diffraction also occurs when a wave passes through a gap (or slit) in a barrier.
This is shown in the animation below (Note: Flash Player 7 required). Try dragging the slider to change the size of the gap. How does this affect wave diffraction?
