2. 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

3. How waves diffract?
• Waves can go
through a hole in a
barrier and spread
out. Or
• Waves can bend
around a barrier

4. Diffraction
• It is only significant if the size of the
opening is about the size of the
wavelength.
• Larger openings produce less
diffraction.

5. 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 around
forest trees and carry farther than the short-
wavelength tweets of songbirds.
