Diffraction

Diffraction

1. example

   • The closely spaced tracks on a CD acts as a diffraction to form the rainbow pattern

2. When an object disturbs and creates a bend in a wave, this bending is called diffraction.

3. Diffraction is a property of all kinds of waves including sound and light waves

   • smaller openings produce grater diffraction

4. Disadvantages

   • - When you watch very small objects with a microscope
     • If the size of an object is the same as the wavelenght of light, diffraction blurs the image
     • If the object is samller, the entire image is lost due to refraction
