DIFFRACTION: PLANE WAVES THRU VERY WIDE APERTURE<br />
Aperture Is Larger Than Wave Frequency<br />
<br />
When the aperture becomes larger than the wave frequency, diffraction is reduced and the emerging wave moves forward with less to no curve and has a well defined boundary with an area of no wave.
