Brainly User. Answer: it means the mirror will produce 4 times bigger image then real object ..
What do you mean by magnification is 3?
Magnification m of mirror image is given by, m = , where v is the ditance between image and mirror and. u is the distance between mirror and object. we have m = -3, it means magnification of image is three times ths size of object . Negative sign indicates we get inverted image.
What is the meaning of magnification =- 2?
Magnification to be – 2 means that the image formed is 2 times smaller than the size of the object . If it would be +2 then the image formed is 2 times shorter than the object.
What do you mean by magnification is minus 3?
Explanation: Magnification of image is negative, meaning the image is inverted and real. ... = -3, meaning the real image formed is thrice the size of the object .
What does a magnification value of mean?
Magnification, in optics, the size of an image relative to the size of the object creating it . ... A negative value of linear magnification denotes an inverted image. Longitudinal magnification denotes the factor by which an image increases in size, as measured along the optical axis.
What does a magnification less than 1 mean?
A magnification of 1 (plus or minus) means that the image is the same size as the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object .
What is magnification short answer?
Magnification refers to an action of magnifying something . Furthermore, it refers to enlarging the apparent size and not the physical size. This enlargement is certainly quantifiable.
What does it mean if the magnification is negative?
The magnification is the height of the image divided by the height of the object. ... A negative magnification indicates that the image is inverted . If the object is placed closer to a converging lens than the focal length, the rays on the far side of the lens diverge.
Explanation: if v is the image distance and u is the object distance .
What is the formula for magnification?
Magnification (m) = h/h’
And h’ is the image height and h is the object height.
Can a mirror have magnification 3 justify?
(i) From magnification of +3, we can say that image formed is magnified and virtual . This type of image can be only formed by concave mirror. (ii) Concave mirror will form magnified virtual image when object is placed betn pole and focus. [Refer to the image for ray diagram.]
Which mirror can produce magnification of +3?
a concave mirror produces a 3 times magnified real image of a object placed at 10 cm in front of it.
How can you identify three types of mirror without touching?
- Plane mirror – If image is upright, of same size and it does not change in size by moving the mirror towards or away from the face.
- Concave mirror – If image is upright and of bigger size and increases in size on moving the mirror away.
What are the 4 types of magnification?
- Relative-size Magnification.
- Relative-distance Magnification.
- Angular Magnification.
- Electronic Magnification.
What is difference between magnification and magnifying power?
Explanation : Magnification – magnification is equal to the ratio of size of image and size of object . ... Magnifying power – magnifying is equal to the ratio of the dimension of the image and the object. So, magnification gives how many time the image has been magnified by instruments.
What does total magnification mean?
Total magnification = Objective magnification X ocular magnification . So for 10X objective and 10X ocular, Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size). For a 40X objective and 10X ocular, Total magnification = 10 X 40 = 400X.
