The object and image distance are interchangeable, because this gives rise to points of conjunction, a point on an object has a conjugate point on the image, both will yield the same value for f and it is a property of optical systems known as reversibility.

If the image distance from a len is 5cm and the object distance is 7.5 cm what is the focal length of the lens?
Use the thin lense equation. 1/f = 1/d + 1/o, where f is the focal length, d is the image distance, and o is the object distance.
Which factor most influences the image produced by reflection of an object in a concave mirror?
distance from mirror
What is a virtual image?
In optics, a virtual image is an image in which the outgoing rays from a point on the object never actually intersect at a visable point. However, if these rays were stretched out they would intersect at a point behind the mirror/surface.
An object is located 51 millimeters from a diverging lens the object has a height of 13 millimeters and the image is 3.5 meters how far in front of the lens is the image located?
13.7 millimetersThis answer is correct, but the formula is most important.The formula is:Hi = height of imageHo = height of objectSi = Distance of image from lensSo = Distance of object from lensYou are trying to find Si, so that is your unknown.Here is your formula: Hi/Ho = Si/SoOr in this case: 3.5/13 = Si/51The rest is basic algebra.Good luck!You can use the ratio equation; (Image Height)/(object height) = - (image location)/(object location) In your case you will get a negative location which means the image is on the same side of the lens as the incoming light.
Which factor most influences the image produced by reflection of an object on a concave mirror?
The focal point. It can affect size, real/virtual, inverted/upright.
What happens to the image distance as the object distance increases?
the focal length of the eye lens is adjusted so that the image distance does not change.
What is the object image distance relationship for a flat mirror?
when dealing with a flat mirror object-distance and image-distance should be equal.
What is the difference between object distance and image distance?
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
How does the distance of the object compare with the distance of the image from the plane mirror?
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
What will happen to pinhole camera if the object distance is equal to image distance?
the image distance will appear the same
What is the relationship between object distance image distance and focal length of concave mirror?
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
What is the relationship between object distance image distance and focal length of a concave mirror?
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
State four characteristics of the image formed in a plane mirror?
1.Image distance= object distance 2.Size of the image = size of the object 3.image is laterally inverted 4.Image is always virtual & erect
What is the definiton of magnification?
It's a ratio of Image distance to the Object distance.
The object distance for a convex lens is 20.0 cm and the image distance is 4.0 cm The height of the object is 10.0 cm What is the height of the image?
2 cm
An object 5 millimeter high is located 15 millimeter in front of a plane mirror How far from the mirror is the image located?
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
What two factor determines the types of image formed by a lens?
The distance of object and the distance of image.
