Which mirror can produce a magnification of 1 3?
Which mirror can produce a magnification of 1 3?
convex mirror
A convex mirror produces a magnification of 1/3, when an object is placed at a distance of 60 cm from it.
What do you mean by +1 magnification?
The magnification produced by a plane mirror is +1 which means that size of the image formed is exactly equal to the size of the object behind the mirror.
Which mirror can produce +1 magnification?
plane mirror
Concave mirror can produce image of magnification -1 and convex mirror always made diminished image so its magnification is always less than 1 and plane mirror always produce image of same size so it will produce image if magnification of 1.
Why the magnification is +1 for a plane mirror?
The magnification produced by a plane mirror is +1 means that the image formed is virtual, erect and of the same size as that of object.
Where should the object be placed to get a magnification of 1 3?
object should be placed at 120 cm in front of mirror to get magnification of 1/3.
What is the magnification of concave mirror?
Solution : (a) The object must be at the centre of curvature of concave mirror. The image formed is real, inverted and of the same size as the object. That is why magnification = – 1.
What do you mean by magnification of plane mirror is +1 when is the magnification positive and negative of the mirrors give reasons?
Magnification =+1 signifies that the image formed in a plane mirror is of same size as the object. Positive sign in the value of magnification signifies that image formed by a plane mirror is erect. Solve any question of Ray Optics and Optical Instrument with:- Patterns of problems. >
Which type of mirror has magnification +2?
if the given spherical mirror has the magnification + 2 then we can understand that the the image formed is virtual and erect and also the magnification is 2 which is greater than 1 so the size of the image is more than that of the size of the object that is the image is magnified.
What is the magnification of convex mirror?
less than one
A convex mirror always creates a virtual image which is diminished. So, magnification produced by convex mirror is always less than one.
Can a mirror have magnification 3 justify?
Expert-verified answer (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.
What is the magnification of mirror?
A magnification of a mirror is 1 .
When an object is placed at a distance of 60 cm from a convex mirror the magnification where the object should be placed to get a magnification of 1 3?
Therefore, the correct answer will be 120 cm.
What is magnification of a mirror?
Magnification of mirrors Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror can be expressed as: m=hh.
What is magnification formula?
Magnification (m) = h / h’ Here, h is the height of the object and h’ is the height of the object. Besides, it can also be related to the object distance and image distance. So, it can be written as: m = -v / u.
What is the nature of the image formed by a concave mirror if the magnification is 3?
What is the nature of the image formed by a concave mirror if the magnification is 3. Since the value of magnification has a positive value the image formed will be virtual and erect. Here the value of the magnification is +3, therefore, the image that will be formed will be virtual and erect.
What is the magnification produced by a plane mirror if the size of the object is 24 cm?
And the height of image formed by plane mirror is equal to height of object. Therefore, Height of Image = Height of Object. Hence Magnification is +1.
What is mirror magnification?
What is the magnification of a spherical mirror is +- 2?
Physical Science if the given spherical mirror has the magnification + 2 then we can understand that the the image formed is virtual and erect and also the magnification is 2 which is greater than 1 so the size of the image is more than that of the size of the object that is the image is magnified.
What is magnification of concave mirror?
The magnification is given by. m = − v u. According to sign conventions, for a concave mirror, the focal length is negative, the object distance is negative, the image distance is positive for a virtual image and negative for a real image.
