on which principle photo states machin works.?

Sorry, everyone will need more information than this to answer this question. I have no idea what is meant by a "photo states machin". Maybe if you add some more information, someone else can answer you.

Unlike traditional cameras that use film to capture and store an image, digital cameras use a solid-state device called an image sensor. These fingernail-sized silicon chips contain millions of photosensitive diodes called photosites. In the brief flickering instant that the shutter is open, each  photosite records the intensity or brightness of the light that falls on it by accumulating a charge; the more light, the higher the charge. The brightness recorded by each photosite is then stored  as a set of numbers that can then be used to set the color and brightness of dots on the screen or ink on the printed page to reconstruct the image\nso Answer A

I would also pick A as the correct answer.\n\nB. the camera might or might not have to be adjusted depending on how much light is being reflected into the picture.\n\nC. A reflector may or may not prevent one side othe image from appearing lighter or darker depending on the actual lighting of the scene.\n\nD. because B & C are not right

No. It has potential energy. When you pull the trigger the potential energy is converted in to kinetic energy that does the intended work.

<Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras. \nThe word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graph꼯span>, together meaning "drawing with light" or "representation by means of lines", "drawing".\n\nImage forming devices\nMost commonly a camera or camera obscura is the image forming device and photographic film or a digital storage card is the recording medium, but other methods are available. For instance, the photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic film, hence the term electrophotography. The rayographs published by Man Ray in 1922 are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. And one can place objects directly on the glass of a scanner to produce pictures electronically. \nPhotographers control the camera to expose the light recording material (usually film) to light. After processing, this produces an image whose contents are acceptably sharp, bright and composed to achieve the objective of taking the photograph.\n\nIf you need more information visit the website below.

Most light microscopes (or at least the ones I used) have a "arrow" in the eye lense that can measure specimens if aligned correctly. It also varied on magnification.

The same reason why a pinhole camera works.  As light passes therough the pinhole, it refracts and is focused.

In this chapter, we’ll look closely at this process because it’s the foundation of everything that follows.

With a scanner and adobe photo Delux shop or a similar program you can do a lot of things by migrating Cartoon images and photos together or like putting buck teeth on someone. It takes a lot of patience and practice but it makes some really neat stuff. I turned my best friend into a blimp doing it and it was hilarious. He liked it too.

SEM scans the surface of the object while in TEM the beam passes through the object\nTEM also have higher resolution

At one time most machines were hand-crafted including rifles.  You could make part A then make part B that would fit it.\n\nMass production of parts that must fit together require any part A to fit any part B and properly work in any finished machine.  Quality Control may insure that all the materials used are correct to prevent unsafe substitutions.  However, experienced designers establish the tolerances for the needed parts to avoid rejects but insure parts will always function properly with required parts lives.  Often tolerances are propritary info and closely guarded because of the expense required to get it right.  Competitors would love to skip all the bother and make an adequate machine at less cost based on someone else's research and experience.  Machinists manufacture the parts to be within the tolerances specified on mechanical drawings.  Quality Control samples the parts to ensure compliance with the drawings and sometimes checks every part if critical.  If tolerances are set too tight costs will escalate and rejects will abound and if tolerances are too loose, machines may malfunction.  The objective is to strike a happy medium (good quality) to manufacture successful machines at reasonable costs.

I am using an Epson 4180 Photo scanner.  Works well for the job.

it works by principle of multiple reflection. This is achieved by keeping mirros in an angle that the light from the base plate gets reflected by many mirrors before travelling your eyes via the cylinder. This is almost the extension of concept where people keep huge mirrors in shop to provide an illusion that it is a big shop.
