In summary, the conversation discusses the difference between real and virtual (or imaginary) images. A real image is physically present and can be seen, while a virtual image is created by the reflection or refraction of light and is not physically present. This can be demonstrated through ray diagrams, where a real image is created when the rays actually meet and a virtual image is created when the rays are extended to meet.

hi, i have an OPTICS question .

i am confused about the "real image" and "imaginary image". could not understand the difference. why a image will be "imaginary image" . images are images. why they have to be imaginary ?

A real image is like when you look at your computer, and see the computer. It is actually there. A virtual or imaginary image is like when you stand two feet in front of the mirror on the wall. You see the 'image' of yourself about 4 feet away, but in reality the object (you) is not there.

In ray diagrams , if you draw the rays being reflected/refracted actually meeting, the image is real and if the lines are to be extended to meet , the image is virtual.
 

What is a real image?

A real image is an image formed by the actual intersection of light rays in space. It can be seen on a screen or surface and appears upside down compared to the object.

What is an imaginary image?

An imaginary image is an image that appears to be formed by light rays, but does not actually exist in space. It cannot be seen on a screen or surface and appears right-side up compared to the object.

What is the difference between a real and imaginary image?

The main difference between a real and imaginary image is that a real image can be seen on a screen or surface, while an imaginary image cannot. Additionally, real images appear upside down compared to the object, while imaginary images appear right-side up.

How are real and imaginary images formed?

A real image is formed when light rays converge at a point after passing through a lens or reflecting off a mirror. An imaginary image is formed when light rays appear to converge at a point, but do not actually intersect in space.

What are some applications of real and imaginary images?

Real images have practical applications in optical devices such as cameras, telescopes, and microscopes. Imaginary images are often used in thought experiments and theoretical models in physics and mathematics.
