Is it possible to make an image permanent?
A photograph taken using a camera is an example of permanent image.
Call me a nit-picker, but the camera obscura was not really a camera in the sense that it was not invented for the purpose of making photographs, and cameras don't develop pictures. If you're asking how long it took to make the first permanent exposure, it was about 8 hours. That being said, the camera obscura was used to make the first permanent photographic image (an image taken in nature). The first permanent image was…
Two knobs are used to get a clear image on low power. The coarse adjustment knob is used to make drastic changes to the image, and the fine adjustment knob is used to make small adjustments to the image. The reason two knobs are used is because you are supposed to get as clear an image as possible on low power before moving on to the next power, and same with medium power.
Is it possible to find whether a mirror is plane concave or convex from the nature of image of an object?
Yes possible. If we place an object somehow close to the mirror and observe the image. If the image is of the same size as that of the object then it is a PLANE mirror If the image is magnified and erect, then it will be a concave mirror If the image is dimisnished then the mirror is convex in nature.

See if you can follow my logic, when u dye your hair, u dye only THAT part of it, as it grows, your natural hair isnt died either so when you get it cut, you cut off the color too, so in reality, there is no possible way to make it PERMANENT.
If you mean created, the first permanent photographic image was created about 1826. However, your question leaves open the possibility that you might be asking about the first image created by exposing a light-sensitive coating. Some say that Leonardo da Vinci invented a form of photography to fake the Turin Shroud in the 1490s! Aside from that, images were created in the early 1700's, but were neither developed or permanent. The first 'developed' image was…
You are a Canadian citizen and marrying a us permanent resident with a missdemenor is that possible?
You don't need glasses to make or print a 3D image. You will need a 3D camera, though. In order to view the image you will need glasses which ensure that the two slightly different perspectives reach the correct eye. This is what gives the impression of being 3D. Bear in mind that the only kind of 3D image possible on paper is an anaglyph (red/blue tinted). The brain interprets the image as 3D but…
