They have a real image.
In a simple microscope, a lens magnifies the image of the sample. in a compound microscope, the objective lens magnifies the image (there may be more than one objective lens) and the eyepiece lens enlarges the virtual image (which is typically inverted by the objective lens).
A focusing screen in a pinhole camera? Uhh...no. A pinhole camera is a box with a very small hole in one end of it and a piece of film in the other end. The screens in reflex cameras and in view cameras are translucent to give the image something to form on. The light will pass through a transparent screen without forming an image, and it won't go through an opaque screen at all.
Yes, and many do as a form of deterrent. Many employers also use hidden cameras, and position dummy cameras to fool employees and patrons.
Refraction
Yes, most digital cameras will allow you to change the quality of the pictures you're taking. Some digital cameras will even allow picture editing and camera effects for the pictures you're taking.
virtual :-)
A virtual image.
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
How to tell if an image is real or virtual is easy. A virtual image is outside object.
virtual image ( not on screen, brain interpreting)
Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen
Convex lens. Concave lens would give only virtual image for real objects.
virtual and real image
Virtual is not what a human eye can see enot like a reael image
A real image in produced by the actual intersection of the reflected rays . Whereas a virtual image is formed when the reflected rays meet after they are produced backwards.
All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.
Real!
