What is the role of lenses used in cameras telescopes and microscopes?
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).
Why is the screen in a pinhole camera translucent?
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.
Can you use dummy videos cameras in a business when you also have real video cameras?
Yes, and many do as a form of deterrent. Many employers also use hidden cameras, and position dummy cameras to fool employees and patrons.
Which property of light waves makes the image formation possible for the eye cameras and other systems of lenses?
Refraction
Do most digital cameras offer the capability to control image quality?
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.
Is the image you see in a plane mirror a real image or a virtual image?
virtual :-)
How can a real image be distinguished from a virtual image and can each type of image be projected on screen?
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
Differentiate real image from virtual image?
Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen
How do you determine whether the images are real or virtual upright or inverted and enlarged or reduced?
To determine if an image is real or virtual, check if the light rays actually converge at the image point (real) or appear to diverge from it (virtual). To determine if the image is upright or inverted, check the orientation of the object and image along the optical axis. To determine if the image is enlarged or reduced, compare the size of the object and the image formed by the lens or mirror.
Does a camera use a diverging lens?
All cameras have converging lenses instead of diverging because they need a real image and not a virtual one to capture a photo.
Is the image formed on a camera film real or virtual?
Real!
Can plane and convex mirrors produce real image?
no it does not produce real image . it produce virtual and erect image
How can you use a screen to determine whether an image is real or virtual?
You can't determine whether an image is real or virtual just by looking at it on a screen - both types can appear identical. To determine if an image is real or virtual, you would need additional information such as its source or creation process.
does a plane mirror produces a real image?
"Real" and "virtual" are two opposite, mutually exclusive categories of images. An image is either one or the other, and no image can be both. The image produced by a plane mirror is a virtual one.
Can a plane mirror form a real image if the object is virtual?
No, a plane mirror will always produce a virtual image regardless of whether the object is real or virtual. The image appears to be behind the mirror and is not a real image that can be projected onto a screen.
What kind of image does a converging lens produce?
A converging lens produces a real or virtual image, depending on the location of the object with respect to the focal point. Real images are inverted and can be projected onto a screen, while virtual images are upright and cannot be projected.
Pictures of real image formed by plane mirror?
When the incident light rays are falling towards the mirror in such a way that the light rays after falling on the mirror meet at any point in front of the mirror than an image is formed in front of the mirror which can be taken on a screen and as the image can be taken on a screen it is known as a real image. So, plane mirrors can form real images.
