Some of these are radio waves, X-rays, infrared rays, Gamma rays and ultraviolet rays. There is one major advantage of non-optical telescopes over optical telescopes and that is non-optical telescopes help the viewers to see things that the naked eyes are unable to. To end the debate of design the reflector, refraction, X-ray and radio telescope were looked at in detail to give you a brief over view
With this telescope, customers have reported that they can see the edge of Pluto on the outer edges of our solar system. That is some really strong viewing capabilities. Revolutionary SkyAlign Feature With the computerized features of this telescope, you'll be able to look directly at the planet or celestial body of your choosing. When you set up the telescope, the internal GPS will establish your position. After that, you will align the telescope by manually positioning for 3 objects in the sky.
The plano-convex lens is replaced with another glass plate and a section of optical fibre was placed between them at one end. Light falling normally on the plates will be reflected back out with a phase difference. Figure 3: Apparatus set up for finding the thickness of an optical fibre, showing the optical fibre between the two glass plates This is due to the fact that some of the coherent light waves were reflected from the top plate and others from the bottom, this path difference resulted in the interference of these waves with one another. This caused an interference pattern similar to the below image: Figure 4: Image similar to the observed interference pattern.  This pattern is also linked to Equations 1&2 as stated previously.
The Keplerian Telescope: image source The Keplerian telescope has two lenses, both the objective and eyepiece lenses are convex (converging). When light parallel to the principal axis passes through the objective lens, the rays refract and converge until they hit the focal point. After they pass the focal point, the rays start to diverge. The rays are then intercepted by the eyepiece lens where the light refracts as it passes through the lens and causes the light rays to become parallel again as discussed in Converging Lens. The image produced by a Keplerian Telescope is magnified, inverted and virtual.
the retina, not on the retina, because the cornea bends the rays too much or the eye was stretched too long, the eye is myopic, or nearsighted. To bring this eye into focus, the rays must be diverged (actually, less converged) so that the point of focus is on the retina. When the rays meet or focus in front of the retina, they cross and are diverging when they hit the retina. Instead of a point of light on the retina, they cast a blur circle. When the many points of an image become overlapping blur circles, the image is blurred and fine detail is lost.
The objective lens has a larger focal length than the eyepiece lens because the objective lens must collect light from a distant object and then refract and ‘channel’ it to the eyepiece end of the telescope. The eyepiece lens, on the other hand, doesn’t need to have a large diameter or focal length because its job isn’t to collect light, but to magnify the image formed by the objective lens. This means the length of a telescope from one lens to the other is approximately the sum of the focal lengths of the two
Thus the delicate part (the mirrors) of the system can be rigidly fixed. The image width at the absorber is ideally the same as projected the projected width of mirror element. Thus, the concentration ratio is approximately the same as the number of mirror elements, ignoring the solar beam spread .As the aperture is fixed and concave in shape ,the mirror strips result in shading with very high or very low sun altitude angles .Also due to strips ,edge losses occur during reflection .However, mirrors can be suitably designed to have less than 10% of the total energy lost over a years time .Some models have shown overall efficiencies in the range of
While using deep focus photography, a cinematographer may have to rely on framing, lighting, or composition to guide an audience in a way that typically would be done by focusing on objects or characters in the foreground of a shot. Many of these techniques are found in the scene which shows young Charles playing in the snow while his mother completes the transaction to have him taken from his home. Throughout the scene, Charles can still clearly be seen through the brightly-lit window, even while the adults are talking in the foreground of the shot. The ability to see Charles at all times emphasizes that although he is not directly involved in the conversation, he is still the topic of interest. This deep-focus aids in the mise-en-scéne of this scene by allowing the cinematographer to strategically include Charles as a focus of the scene without directly involving him in the dialogue.
In a compound light microscope, there are two lenses, one is the ocular (the eyepiece) which is at the top of the microscope and typically magnifies objects four to ten times. The other lens is the objective lens, typically located just above the mechanical stage; classically there are four different viewing objectives with this type of microscope, 4x, 10x, 40x, and a 100x oil immersion objective. Because the object is viewed with two different lenses at the same time, the objective lens is being magnified to the 10x power due to the low power objective of the ocular lenses, as well as the amount on the objective lens. For instance if the specimen is being viewed with a 4x objective, the magnification level would actually be four times ten for a total of 40x. Each objective level will be multiplied by 10 for the exact magnification
The eyepiece lens consists of one lens, and that’s where you look through. The tube below the eyepiece lens connects it with the objective lenses (ultimate power of magnification). The eyepiece lens has a magnification of 10x (likely to most basic optical microscopes), and the objective lenses- which can consists of three to four lenses, usually have the magnification power of 4x, 10x, 40x and 100x. While the eyepiece can magnify about 10x, the total magnification would be 40x, 100x,
