Can we see virtual image?
Although a virtual image does not form a visible projection on a screen, it is no sense “imaginary”, i.e., it has a definite position and size and can be “seen” or imaged by the eye, camera, or other optical instrument.
A reduced virtual image if formed by a single negative lens regardless of the object position..
Can we see real image?
No, real images cannot be seen without a screen. A real image can be viewed on a screen, a virtual image can not. Rays from both types can enter your eye, be refracted by your eye’s lens and form a real image on your retina as @CarlWitthoft points out.
What type of image is formed in a plane mirror and on a cinema screen?
Answer. The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.
What is a cinema screen made of?
Most screens are made of vinyl coated with magnesium carbonate, which looks like white chalk and has the unique property of being perfectly reflective – it absorbs no light, scatters light equally in all directions, and has a gain of 1.0.
What is the difference between real and virtual image?
A real image and a virtual image are different forms of image. The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge.
How do you know if an image is erect or inverted?
When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright. A negative m means that the image is inverted. Positive means an upright image.
Why are real images always inverted?
Originally Answered: Why are real images always inverted? … Since rays are only converged by a concave mirror or a convex lens towards their center, rays can only meet below the X-axis if the object is above the X-axis, hence real image is formed inverted in all planes with respect to the object.
Why we can see our image in a mirror?
We all use mirrors at home. … An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected. So, light incident on any smooth shiny surface like a mirror bounces back into the same medium. This bouncing of light by any smooth surface is called reflection of light.

Can an image be formed without a screen?
Well actually the image is formed on your retina inside the eyes and you are able to see the refracted rays after they intersect in air. Thus you see the real image without a screen . Images are perception of any light reflected from a source. So ,in short, No , you can’t see an image without a screen.
Are virtual images always upright?
Virtual images are always located behind the mirror. Virtual images can be either upright or inverted. Virtual images can be magnified in size, reduced in size or the same size as the object. Virtual images can be formed by concave, convex and plane mirrors.
