Compared to its actual size how will an object seen through a convex lens appear?
LARGER!!
Convex lensWhat type of image is seen from the lens?
A virtual, enlarged and erect image is seen from the lens. Here from means through the lens. This is what a palmist does while reading the lines on the palm to foretell the future.
An object seen close up through a convex lens looks than it really is?
A convex lens is a mirror whose middle is larger than the top and bottom. A convex lens is more than two focal lengths. It is smaller and inverted between one and two focal lengths.
Where should an object be placed in front of a convex lens to get a real image of the size of the objects?
The image seen through a convex lens will appear upright and enlarged when the object being viewed is within the focal length of the lens.
Why is a magnifying glass considered an Optical Device?
Because a magnifying glass is made of of convex lens. It converses light rays and magnifies the objects seen through it.

Why are rings circular in newtons rings?
Since a plano-convex lens is being used in Newton's Rings .. that's why=the fringes are seen circular from above, on the glass plate.=
Does a convex lens invert images?
Yes. Image formed by convex lens is laterally inverted. However, It should be kept in mind that convex lens can form both real and virtual images. If the object is placed beyond F (Focus), then real image will be formed and laterally inverted. However, if the object is placed between F and C. Then the images formed will be virtual but NOT laterally inverted. For concave lens, all images formed is on the same side so the images formed is NOT laterally inverted
Why convex lens of short focal length is preferred on magnifying glass?
The power of a lens is measured in dioptres which is the reciprocal of the focal length in metres. A 5-dioptre lens would allow you to see something at a distance of 20 cm, while a 20-dioptre lens would allow the object to be seen from 5 cm (2 inches) so it would be more effective as a magnifying glass. Your arms are short.
Why convex mirrors are used in shopping malls?
Convex mirrors are used as driving mirrors because they give drivers a much larger field of view without needing to move their heads from side to side.
Why are the fringes circular in newton's rings?
intensity of ring formed depends upon the thickness of air coloumn b\w the lens & glass plate.and the locus of points having same thickness of aircolumn is a circle,with the center as the point of contact of b\w the glass plate and lens.
What is mild convex thoracic scoliosis?
A mild convex right thoracic scoliosis is when the spine is curved toward the right. It can be seen on an x-ray of the spine.
Which lens of a microscope is responsible for producing a magnified image on the inside of the microscope that is not seen directly by the person using the microscope?
to produce a magnified image, a microscope uses 2 convex lenses which have relatively short focal lengths to magnify small, close objects.
