What happen when put convex and concave With some?
When a convex lens and a concave lens are placed together, they can form a compound lens system known as a lens system. Depending on the relative orientations and distances between the two lenses, the resulting system can either magnify, diminish, or correct the incoming light rays. This configuration is commonly used in optical instruments such as microscopes and telescopes to manipulate the path of light rays.
Why is chromatic aberration more evident for some positions of the aperture?
The further the aperture is from the optical axis of the lens, the more to the side of the lens the incident light falls. The further the light falls from the optical axis, the greater the effects of chromatic aberration. This is because different wavelengths of light have different refractive indices (dispersion). Because of Snell's Law, n1sintheta1=n2sintheta2, the greater the angle of incidence, the more pronounced the effects of the difference in refractive indices. Spherical aberration further enhances the chromatic dispersion.
What are some examples of visible light being utilized in real life applications?
Some examples of visible light being utilized in real life applications include photography, microscopy, barcode scanners, and optical communication systems.
Where are lens are used?
Lens are widely used. The most common example of the usage of lens is the spectacles. The spectacles contain either convex or concave lenses. In some cases it is plane. Convex Lens are widely used in Magnifying glasses, Microscope and Telescopes. Convex lens are used in torch lights. It helps in concentrating the light rays emitted from the bulb to a point, hence increasing the intensity of light at that point.
What jobs deals with light waves?
Some jobs that deal with light waves include optometrists who study how light interacts with the eye, optical engineers who design and develop optical systems, and astronomers who use light waves to study celestial objects in space. Electrical engineers and physicists also work with light waves in areas such as telecommunications, fiber optics, and photonics.
What is an easy definition of the optical axis?
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
What is optical hardware?
Optical networking hardware entails the various components used in optical technologies. Some of the common hardware include routers, optical fiber, electronic devices and so much more.

What replaced glass in lense design?
Plastic materials, such as polycarbonate and CR-39, have replaced glass in some lens designs due to being lighter, more impact-resistant, and more affordable. These materials can still provide excellent optical quality for eyeglass lenses.
What are ocular lenses?
They are curved transparent materials that make light rays come together or spread out.or a lens is a transparent material which has one or more surfaces curved for the purpose of deviating light raysA lens is an optical element that can transmit and refract light, by converging or diverging the beam. Simple lens is a single optical element. Compound lens is an array of simple lenses having a common axis.

Why do astronomers use as few lenses as possible in their telescopes?
Astronomers use fewer lenses in telescopes to minimize light loss due to absorption and reflection by the lenses. Each additional lens in the optical path can reduce the amount of light that reaches the eyepiece, affecting the image quality. Additionally, fewer lenses can help reduce chromatic aberration and other optical imperfections.
What is an optical view finder?
An optical viewfinder is a separate aiming device for a camera, that is by definition fitted with its own lens or lenses, and which shows the photographer roughly the same field of view as the taking (or camera) lens. Some optical finders on zoom cameras will zoom with the taking lens. Most optical finders show a smaller percentage of what the taking lens "sees" so that there is a margin for error. Once, almost all cameras that were not reflex (that is, the finder image is projected from the camera lens) were fitted with optical viewfinders. Many small digital cameras today have no optical viewfinder, using only the view screen instead, but while the view screen usually shows a nearly 100% accurate view of the scene, the screen may be partly or wholly obscured in very bright light. An optical viewfinder can be handy in such situations. If you're using a camera with only a view screen with the sun coming over your shoulder you may have found yourself wishing that you had an optical viewfinder. There are other types of viewfinders, not all of them optical. Many older "press" type cameras such as the Graphics had a wire frame finder, often called the "press" finder, which just gave the photographer a rough aiming point, but which was very useful when the picture was fleeting. The big 4x5" press cameras had the advantage that a usable image could easily be cropped out the ample negative, so very accurate viewfinding was not always necessary.
What are some common optical illusions questions that people often ask?
Some common optical illusion questions that people often ask include: "How does an optical illusion trick our brain?" "Why do some people see optical illusions differently?" "Can optical illusions be used to study the brain?"

What is used for final focusing?
In optical systems, a lens is typically used for final focusing to converge light rays to a single point or plane. The focal length of the lens determines the distance at which it needs to be placed to achieve proper focus. Other methods for final focusing include mirrors, phase plates, or diffractive elements in certain applications.
