Diffraction

Diffraction

1. Is a property of all kinds of waves, in

2. Is a property of all kinds of waves, in which the waves bend around the edge of a barrier or through an opening in a barrier

   • Smaller openings produce greater diffraction

3. Is not confined to narrow slits in general, but can be seen around the edges of all shadows

4. If the size of an object is about the same as the wavelenght of light, diffranction blurs the image

   • If the object is smaller than the wavelenght pf light, no structure can be seen
     • The entire image is lost due to diffraction

5. Examples

   • - When you hit a piece of wood inside a container with water, the water would ripple and make waves around the piece of wood
     • - The rainbow pattern in a CD
       • - If a wave meets a hole in a wall that is of comparable size to its wavelenght, the wave will be bent
