Diffraction

Diffraction

1. WHAT IS?

   • Is any bending of light by means other refelction and refraction.

2. EXAMPLES

   • Plane waves passing through openings of various sizes. As the opening is narrowed the waves spread more. Smaller openings produce greater diffraction.

3. PROBLEM

   • When you are viewing very small objects with a light microscope. If the size of an object is about the same as the wavelanght of light, diffraction blurs the image. If the object is smaller than the wavelenght of light, no structure can be seen. The entire image is lost, due to diffraction.

4. CHARACTERISTIC

   • Is a porperty of all kinds of waves, including sound and light waves.
