Optics is the branch of physics which studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as Xrays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be accounted for in geometric optics. Historically, the raybased model of light was developed first, followed by the wave model of light.

Originally published in 1878 as part of the Natural Philosophy Series. A detailed and well illustrated book dealing with every aspect of Optics and Optical Instruments plus the analysis and theories of light. Contents include: Luminous and Nonluminous Bodies Light Reflection of Light Refraction from Varied Surfaces Properties of Lenses Analysis of Light and Chromatic Aberration Theories of Light Polarisation The Eye Optical Instruments Spectacles Microscopes Telescopes Cameras Stereoscopes Kaleidoscopes Magnifying Glasses etc. Many of the earliest scientific books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. Home Farm Books are republishing many of these classic works in affordable, high quality, modern editions, using the original text and artwork.

In the thirtyseven years that have gone by since the first volume of Progress in Optics was published, optics has become one of the most dynamic fields of science. At the time of inception of this series, the first lasers were only just becoming operational, holography was in its infancy, subjects such as fiber optics, integrated optics and optoelectronics did not exist and quantum optics was the domain of only a few physicists. The term photonics had not yet been coined. Today these fields are flourishing and have become areas of specialisation for many science and engineering students and numerous research workers and engineers throughout the world. Some of the advances in these fields have been recognized by awarding Nobel prizes to seven physicists in the last twenty years. The volumes in this series which have appeared up to now contain nearly 190 review articles by distinguished research workers, which have become permanent records for many important developments. They have helped optical scientists and optical engineers to stay abreast of their fields. There is no sign that developments in optics are slowing down or becoming less interesting. We confidently expect that, just like their predecessors, future volumes of Progress in Optics will faithfully record the most important advances that are being made in optics and related fields.

Rhode Island Lighthouses
When I think about Rhode Island, a nice picture comes to my mind with hilly, rocky beaches and picturesque lighthouses. These wonderful, mostly white buildings are familiar in New England. There are plenty of lighthouses in the smallest state of the United States, Rhode Island. You can visit over 20 lights, all located in a close geographical area.
First, there is Castle Hill, Newport. This light was built around 1890, stands forty feet above sea level and marks the east entrance of Narragansett Bay. It can be seen from about twelve miles away. The Richardsonian Romanesque style lighthouse flashes an intermittent red light every six seconds to warn sailors. It is situated in a beautiful, untouched environment, you can only meet the keeper or some seagulls here.
In Narragansett, you'll also find Point Judith, which was built in 1810. This light guards the western entrance to the bay. In 1931 it became the first station in Rhode Island to have a radio beacon. These beacons allow ships to navigate at night or in fog without depending upon the light or the foghorn.
Another nice one is Newport Harbor Light at the north end of Goat Island, New Port. The current light was constructed in 1842 and has a height of 33 feet. The light was electrified and the present optic is 250 mm and is fixed green. The Newport Harbor light is an active U.S. Coast Guard aid to navigation and is managed by 'Friends of Newport Harbor Lighthouse.'
Watch Hill, Westerly is located on the north side of the east entrance to Fishers Island Sound in Rhode Island. It is situated on a peninsula that is almost surrounded by ocean, giving breathtaking beauty to this area. If you would like to see magnificent sunsets, you must come here. The silhouette of the lighthouse is awesome. Otherwise the whole town is wondrously interesting, full of history, Victorian architecture, classic Rhode Island oceanfront 'cottages', white sand beaches, good fishing spots, and so on. The Watch Hill Inn, built in 1845, furnished in a traditional New England style, is the town's gem, too.
And finally Rose Island, which is located in the middle of Narragansett Bay just south of the Newport Bridge. This place is a real curiosity. Can you imagine how it feels to stay in a lighthouse overnight? Here, you can try it. You can book a stay at Rose Island Lighthouse. What's more, you can be a keeper for a week, too. You have to sign for an environmental education program, where people of all ages learn about the Lighthouse's history and they experience first-hand the keeper's self-sufficient, resourceful way of life. You'll have some duties, most importantly making sure the windmill generates enough power to keep the light burning through the night. A small wind turbine powers the lighthouse and lighting inside the museum - there is no radio nor TV, no Internet, nothing. You may enjoy the beauty of the nature and freedom undisturbedly, you can collect shells and orange starfish. Isn't it wonderful?
