His name graces a set of equations, applicable to electromagnetic radiation incident on a dielectric, which determine the ratio of transmitted and reflected electric field amplitude to the initial electric field. He also has a device which makes use of constructive interference, called his "zone plates," and a "number" calculated as the aperture radius squared over the wavelength times distance from the aperture. When that number is approximately equal to 1, his "diffraction" occurs. For 10 points, name this physicist who also assembled concentric rings of glass into a device useful in lighthouses, known as his "lens."
