What is the minimum distance between an object and its real image formed by a convex lens?
Find the smallest distance between the object and a real image, when the focal distance of the lens is
2. Relevant equations
, where
is the distance of the object from the lens and
is the distance of the image.
3. The attempt at a solution
I'm not even sure, what I'm trying to do here, since the definition of a real and virtual image is a bit vague to me. But I've got something...
Let
be the desired distance. From the equation above we get
so
. Then
or
. We get the same for
, so the distance would be

What is the relationship between bonds and electronegativity?
If the electronegativity difference between the two atoms is above 1.7, then ionic bond is formed and if the difference is below 1.7, then covalent bond is formed.
What is the difference between igneous and sedimentary rocks?
Igneous rock is formed from the solidification of magma or lava. Sedimentary rock is formed from the lithification of sediments, generally.

Circle shape meaning?
In geometry, a circle is a two-dimensional shape formed by all points that are one consistent distance or "radius" from a single central point. For example, if the radius is 5 inches, then the shape formed from the preceding rule would be a perfectly round circle measuring 10 inches in "diameter" (the distance of any one point on a circle to the farthest point on the same circle).
How does the distance between an object and a convex lens affect the image formed?
The distance between an object and a convex lens affects the position, size, and orientation of the image formed. When the object is placed beyond the focal point of the lens, it forms a real and inverted image. When the object is placed between the focal point and the lens, it forms a virtual and upright image.
The image formed by a convex mirror?
The image formed by the convex mirror is virtual, erect and diminished.
The image formed by a convex spherical mirror will always be what?
The nature of the image is not constant. It varies with the distance between the object and the mirror.
A tree is located between a convex lens and its focal point. Which answer describes the image of the tree formed by the lens?
The image of the tree formed by the convex lens is virtual, upright, and magnified.
What does the image formed by convex lens depend upon?
The image formed by a convex lens depends on the object distance from the lens, the focal length of the lens, and the object size. These factors determine whether the image formed is real or virtual, magnified or diminished, and upright or inverted.
What are the characteristics of images formed in a convex mirrors?
Images formed by convex mirrors are virtual, upright, and diminished in size compared to the object. They are always located behind the mirror and the image distance is negative. The image is formed by the intersection of reflected rays that appear to diverge from a point behind the mirror.
When does a convex lens forms a real or virtual image?
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
What image is formed by a convex mirror?
The image is always virtual,smaller,and erect at any distance in which the object is placed.
How would you describes the image formed by a convex mirror?
The image formed by a convex mirror is upright and larger than the object.
How is an image formed by a convex lens?
An image is formed by a convex lens when rays of light converge after passing through the lens. This forms a real image on the opposite side of the lens. The position and size of the image depend on the distance of the object from the lens and the focal length of the lens.
How could I use a convex lens to create an image of an object that is smaller than the original?
To create a smaller image of an object using a convex lens, place the object between the lens and the lens' focal point. This will result in an inverted, smaller image being formed on the opposite side of the lens. Adjust the distance between the lens and object to control the size of the image.
What is the nature of image formed by a convex lens?
A convex lens forms a real or virtual, inverted or upright image, depending on the object distance and the focal length of the lens. The image can be either magnified or reduced in size compared to the object.
