State whether true or false :
The correct option is A True
Real images: A real image is an image formed by actual
rays of light. Real images are always inverted, and they may be either larger
or smaller than the object.
Virtual images: An image, that seen in a mirror, in
which the rays of light appear to be emanating from some object that is not
there is called a virtual image. Virtual images are always erect. They, also,
may be either larger or smaller than the object.
A slide projector produces a
real, inverted and magnified image. The image must be real, because otherwise
you would not be able to project it onto a screen. The image is inverted, so
the slides have to be put in upside down. A projector uses a convex lens. A
magnifying glass also uses a convex lens. The image is upright, magnified and virtual.
The object must be at or within the focal length of the lens.
