To produce a focused image on a screen, the light emitted or reflected from the image source (such as a projector or display) needs to be accurately converged to a single point on the screen. This convergence is achieved by adjusting the optics of the projection system or the display settings to ensure that the light rays are correctly aligned and focused at the proper distance on the screen, resulting in a sharp and clear image. Regular maintenance of the equipment and ensuring proper alignment also help in producing a focused image on the screen.
Yes. That's a good quick way to determine whether or not a real image exists. You can also use a piece of thin tissue paper, kleenex, or toilet paper, and see the image from the other side. Put a piece of photosensitive material there at the real image, and you get a permanent photo.
A slide projector works by shining light through a transparent slide containing an image and projecting that image onto a screen or surface. The light source inside the projector illuminates the slide, which is then magnified and focused through a lens to create a larger image for viewing. The slides are manually advanced to display different images in sequence.
A concave mirror would be used to project an image on a screen. This type of mirror is able to converge light rays to a focal point, creating a focused image on the screen.
A concave lens can produce a real image for a virtual object by refracting light rays in such a way that they diverge as if they originated from a point behind the lens. This creates an image that can be projected onto a screen or surface. The lens helps spread out the light rays, creating a focused image that can be seen.
virtual image ( not on screen, brain interpreting)
A stream of electrons is accelerated by several thousand volts, & focused on to a phosphorescent screen in a CRT (cathode ray tube) commonly known as a picture tube.

reduce the amount of exposure required to produce an image.
To take a photo of a screen without any lines appearing in the image, adjust the camera angle to reduce glare and reflections on the screen. Additionally, ensure the screen is clean and the camera is focused properly to capture a clear image.

No you dont need a screen, you could just use a wall
In a cathode ray oscilloscope (CRO), the anode serves to accelerate the electrons emitted by the cathode towards the screen at the other end of the tube. This acceleration helps to produce a focused beam of electrons which can then be deflected by the electric or magnetic fields to create an image on the screen.
A transmission electron microscope (TEM) image is created by passing a beam of electrons through a very thin specimen, which interacts with the specimen to produce an image. The electrons that pass through the specimen are then focused using a series of electromagnetic lenses to create a magnified image on a fluorescent screen or camera. The contrast in the final image is generated by differences in the specimen's electron density.
No, a concave lens alone cannot form a real image on a screen. Concave lenses always produce virtual, upright, and diminished images.
