DIFFRACTION

DIFFRACTION

1. IS...

   • When waves bend around obstacles making the waves spread out

2. Waves spread out when they pass a gap or obstacle

3. Amount of diffraction depends on the size of the gap depending on the wavelength of the waves

   • Light can be diffracted but needs a v small gap because it has a small wavelength

4. A narrow gap is one that is the same as the wavelength f the wave

   • The narrower the gap or the longer the wavelength, the more the wave spreads out
