A 2cm tall object is placed perpendicular to the principal axis of a convex lens of focal length 10cmThe distance of the object from the lens is 15cm Find the position nature and height of the imag?
An image formed by a convex lens is described by the lens equation 1/u+1/v=1/f, where u is the distance of the object from the lens, v is the mage distance from lens and f is the focal length of the mirror. The question states that f=10cm and u=15cm, This can be substituted in the lens equation as follows: 1/15+1/v=1/10 1/v =1/30 V=+30 Magnification =v/u =30/15=2. The positive sign of v means the image is real, inverted and it on the opposite side of the object. Solution: The image is twice the same size as the object, real, inverted and on the opposite of the object.
How do you decrease the size of a circle?
Decrease The Length of The Radius
How do you decrease he size of a circle?
By reducing its radius or diameter.
What is the number of cubes a 3-d object can hold?
That depends: * On the size of the 3D object * On the size of the cubes
What is an object line for drafting?
it is a heavy line that defines the shape and size of an object in a blueprint
If the image produced by a lens is the same size as the object then the lens must be?
convex lens at 2c
Why does the lens flip and decrease the size of the picture in a camera?
The lens is convex (curved outward). Light entering the lens from the outside is refracted (bent) as it travels through it. This brings the image to a single (focal) point. The distance between the lens and the back of the camera is such that it allows a small image of the photographed scene to be visible (the picture). The image is inverted because of the refraction of light through the lens.
What happens to an object if you move it closer to a concave lens?
As an object moves closer to a concave lens, the virtual image, that is created on the same side of the lens as the object, will remain upright but will be reduced in size.
What type of lens will produce a virtual image longer in size that of object?
This is possible only with a convex lens but with a condition that the object has to be placed in between the optic centre and principal focus of the lens.
Why does the field of view decrease as the power of objective lens increase?
There is a relationship between the power of an objective lens and its field of view. As the power of the objective lens increases, the size of its field of view decreases
What happens to the image formed by convex lens if the object is moved closer to the lens?
The image becomes blurred and it's size increases.
Compared to its actual size how will an object seen through a concave lens appear?
SMALLER
Compared to its actual size how will an object seen through a convex lens appear?
LARGER!!
What is the focal length of a converging lens which produces a virtual image four time the size of the object the image being 15 cm from the lens?

An object is located 15millimeters from a diverging lens the object has a height of 13 mm and the image height is 3.5 mm how far in front of the lens is the image located?
Using the expression v/u = Image size / object size we can find the value of v. v = 15 * 3.5/13 = 4 (nearly) So approximately at a distance of 4 mm in front of the lens the image is located on the same side of the object.
Place an object between a magnifying lens and its focal point the image is?
Place an object between a magnifying lens and its focal point. The image is right side up and larger than the object
How does lens reduce the size of objects?
Well it doesn't actually, I assume mean the appearance of size. If so it's due to the curvature of the lens the light reflects off the lens differently causing the light to bend and make said object appear smaller.
