What is Diffraction?
• Diffraction
–the bending of waves around the edge or the corner of a barrier
–Amount of diffraction is dependent on the wavelength and size of the opening barrier
How waves diffract?
• Waves can go through a hole in a barrier and spread out. Or
• Waves can bend around a barrier
Diffraction
• It is only significant if the size of the opening is about the size of the wavelength.
• Larger openings produce less diffraction.
Examples
• The spreading out of waves in the oceans.• A laser beam scatters after passing through a
small slit.• Sound diffracting around corners or through
door openings• Owls are able to communicate across long
distances due to the fact that their long-wavelength hoots are able to diffract aroundforest trees and carry farther than the short-wavelength tweets of songbirds.
