What is the difference between the object and the image?
image larger than object
What is meant by conjugate points with respect to a lens?
The object- and image-points of a particular lens are described as conjugate. The object point, or the point at which the image is taken from, and the image point, the image itself, are able to be flipped perfectly, as if the object is placed where the image was, an image will appear where the object was.
Why is the image of an object reflected from plane mirror called a virtual image?
Because the image is not real. The object is not really there, it's only virtual.
What type of image is formed when object is kept at F for a convex lens?
For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.
What are the properties of images of a plane mirror?
The image is equivalent to object in magnitude implying that the image is of the same size as the object.
Why you need remote sensing image classification?
in order to to differentiate different object of the image like building, roads ad vehicles
Differentiate computing from computer?
computer is an object computing is what you do on the object (computer)
What is the difference between the object and the image?
image larger than object
With five examples or illustration, differentiate between ICT and icts?
[object Object]

What is the difference between an object and an image?
An image is an optical representation of an object.... Object is real... while image is not... i thnk the word imaginary fits for image.... we can take example of our shadow... when light falls on us ( object ) it creates an image (shadow ) in the ground....
Differentiate real image from virtual image?
Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen

Which types of imags are produced by concave mirrors?
real and virtual images

How diverging lens can produce images that are smaller than the object?
When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.

What is difference between erect and inverted image?
If the image is upside up view of the given object than it is called Inverted Image. If it remains as the object than it is called Erect Image
