What is the relationship of the size of object and image to the distance of the object and image?

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.

∙ 14y agoFocal length is effective focal length of lense system, focal distance is distance (from some point in system) to focused picture. Strictly speaking, this varies as object moves nearer from infinity to system. In case of single (thin) lense, focal length is the same as focal distance from the lense, when object is in infinity.
In case of teleobjective, mirror telescope etc., focal length can be much larger than the length of the optical system. Then it is convenient to define e.g. BFL = Back focal length, which is the distance from last lense to focus point. Correspondingly, wide-angle camera lenses have much larger focal distance (and BFL) than focal length in order to give space for lifting mirror in SLR cameras.

- For convex mirror, an object is impossible to be placed at the focal point, because the focal point is behind the mirror.
- For concave lens, all images formed are virtual, upright, diminished and is formed in between the object and lens.
- For convex lens, the image formed is virtual, upright and is formed at infinity. However, the size of image cannot be determined.

(1/p) + (1/q) = 1/f

In case of both mirrors and lenses, the image distance is dependent on the object distance.

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 are the 5 Properties of an image in a plane mirror?
Characteristics of an image formed by the plane mirror are :- * Virtual and erect (up right ) . * The image is of same size as that of the object . *The image is far behind the mirror as the object is in front of it . *The image is laterally inverted .
Describe the image formed in a plane mirror?
image form by plane mirror are virtual,upright,left- right reversed,the same distance from the mirror as the object's distance,and the same size as the object.............that's all
What describes image formation by a plane mirror?
The image in a plane mirror is the same size as the object, the same distance from the mirror, upright and laterally inverted.
A convex lens forms a real and inverted image of a needle at a distance of 50cm from the lensWhere is the needle placed in front of the convex lens so that the image is of the same size as the object?
A convex lens forms a real and inverted image of equal size only when it is kept at the center of curvature of the lens. The image is also formed at the center of curvature at the other side. Hence, the distance of object = distance of image = 50 cm. Now, focal length = � � radius of curvature = � � 50 cm = 25 cm Hope it is clear!

What will happen if object distance is decreased in pinhole camera?
If the object distance is decreased in a pin hole camera, the image size will increase. If the object is too close, the full image will not be formed and the screen will appear dark.
List 5 properties of a virtual image creaed by reflection from a plane mirror?
1. Image is upright 2. Image is virtual 3. Image is of same size as object 4. Image is laterally inverted 5. Distance from object to mirror is equal to the distance from the mirror to the image

What is the ratio of the size of the image seen with the microscope to the actual size of the object?
There is no constant ratio for image size to object size It depends on, 1. Image size 2. Sensor specifications (ex: Focal length of the camera) 3. Camera to Object distance 4. Acquisition angle (Theta) 5. Light focusing 6. Need some Known object values for determine unknown object size etc...
What describes image formation by a plane mirror?
The image in a plane mirror is the same size as the object, the same distance from the mirror, upright and laterally inverted.
Magnification factor in x-ray?
Your magnification factor is SID divided by OID. [MF = SID/OID] So for example: If your SID was 40 and your SOD was 32 Your magnification factor = 40/32 = 1.25 -- This means the image will appear 25% larger than the actual object. (It's the size of 1 plus 25 percent more of the original.) Example 2 if you're trying to figure out original object size: Your object size equals your image size divided by the magnification factor (MF). [object size = image size/ MF] If you have an object on an image that measure 70 inches when your SID was 100 and your OID was 65, how big was the original object? MF=100/65= 1.54 (rounded) Object size = 65/1.54 = 42.21 The object imaged was 42.21 inches before magnification.
What should be the size of a plane mirror to get a full size image of a person?
The size of the plan mirror should be half the size of the object to get a full size image of the object
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.
Describe the image produced by plane mirror?
Usually as we say the details of the image we point out their, size, position, type and nature. In case of plane mirror, size = same size of the object position = at the same distance as the object is in front of the mirror type - erect one nature - virtual image. This means could be seen but not be caught on a screen.
The apparent size of an object is determined by the size of its image on?
The retina
