Optics is the branch of physics that deals with light and its properties and behavior. It is a vast science covering many simple and complex subjects ranging from the reflection of light off a metallic surface to create an image, to the interaction of multiple layers of coating to create a high optical density rugate … See more Light is a type of electromagnetic radiation usually characterized by the length of the radiation of interest, specified in terms of wavelength, or lambda (λ). Wavelength is commonly measured in nm (10-9 meters) or μm (10-6meters). … See more Isaac Newton (1643 - 1727) was one of the first physicists to propose that light was comprised of small particles. A century later, Thomas Young (1773 - 1829) proposed a new … See more While reflection causes the angle of incidence to equal the angle of reflection, refraction occurs when the wavefront changes direction as it passes through a medium. The degree of refraction is dependent upon the … See more Reflection is the change in direction of a wavefront when it hits an object and returns at an angle. The law of reflection states that the angle … See more WebApr 25, 2024 · Optical sights often magnify the target image, thereby aiding positive target identification and precise shot placement.
