and diffraction surface profile are vital before Fourier solutions can be evaluated and in fact each solution is valid only for one configuration In order to arrive at a Fourier optics solution Sta.

Wave Optics. The wave nature of light is needed to explain various phenomena. Interference. Diffraction. The . particle nature of light was the basis for ray (geometric) . optics. Light waves interfere with each other much like mechanical waves do. Diffraction of light when two fingers brought close together . infront of a light source . Diffraction by razor blade when illuminated by intense blue light . “light is never known to follow . crooked passages nor to . Pg. 459 - 461. Properties of Waves. In order to study the properties of waves, a ripple tank is used. A shallow, glass-bottomed tank on left. ~2cm of water is added. Light from a source above the tank passes through the water and illuminates a screen on the table below. Nick Anastas. Outline. Virtual Objects. Phong Reflection Model. Basic Shading Models.
