Parabolic reflector Circular paraboloid. A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. The parabolic reflector transforms an incoming plane wave traveling along the axis into a spherical wave converging toward the focus.

What is an Overhead Projector? An overhead projector is a very basic but reliable tool used to display images onto a screen or wall. It consists of a large box containing a cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen.

Difference Between Refractor and Reflector Telescopes Refractor vs Reflector Telescopes | Refraction vs Reflection Telescopes. Reflector and refractor are basically the main two types of telescopes mostly used in astronomy. They are also known as reflection telescopes and refraction telescopes. These are mainly optical devices, which use visible light to produce images of distant objects, such as planets, stars, nebulae and galaxies.

Flash Diffuser - Lambency Flash Diffuser - Lambency. Also known as a Lightsphere. A lambency flash diffuser is a device that fits onto the front of a flash and both reflects and diffuses the light output, reducing greatly shadows. The flash unit is pointed vertically, and the device fitted, light hits the curved top cap of the unit and this reflects it back through the side.

Collimated light A perfect parabolic mirror will bring parallel rays to a focus at a single point. Conversely, a point source at the focus of a parabolic mirror will produce a beam of collimated light. Since the source needs to be small, such an optical system cannot produce much optical power. Spherical mirrors are easier to make than parabolic mirrors and they are often used to produce approximately collimated light.

Difference Between Refractor and Reflector Telescopes Later it came to be known as the Gregorian telescope. The credit for the first reflector telescope goes to the great Isaac Newton. He built the first reflector telescope in 1668 which later became known as the Newtonian telescope. The Newtonian reflector is the most famous type of telescope among amateur, and most of the professional astronomers.

- Reflecting telescope. A reflecting telescope (also called a reflector) is a telescope that uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives.

Why was the Battle of Midway important? The Battle of Midway was a sea-based battle between the United States and Japan which occurred between June 4th and June 7th, 1942. Named for its location near the Midway island in the Pacific Ocean, the Battle of Midway was important because it was the first decisive victory for Allied Forces in the Pacific during World War II. The United States sunk four Japanese carriers (the only four that Japan brought to the fight) and one heavy cruiser, significantly damaged two destroyers and second heavy cruiser, and destroyed 248 aircraft.

Phasor measurement unit A phasor measurement unit (PMU) is a device which measures the electrical waves on an electricity grid using a common time source for synchronization. Time synchronization allows synchronized real-time measurements of multiple remote measurement points on the grid. The resulting measurement is known as a synchrophasor.

- b) Diameter of the compound parabolic concentrator = 180 mm The overall dimension of solar receiver was 1860 mm in length and 1220 mm in breadth. A total of six parabolic concentrators were placed with equal spacing of 15 mm (Fig. 5) over previously constructed flat plate collector.xperiments were carried to study the comparative performance of a solar flat plate collector and compound parabolic concentrator of same size. Average temperature rise of 9.5 0 C was observed during the period. A manual solar tracking was facilitated along the two axes up to 4.68 0 vertical and 11.54 0 horizontal.
