Where should the object be placed to get a magnification of 3?

For the magnification value of -3, the image formed will be real, inverted and enlarged/magnified. The object must be placed between the principal focus F and the centre of curvature C of the concave mirror.

Where should an object be placed in a concave mirror to obtain a magnification of 3?

A magnification of -3 means that the image is real, inverted and magnified. So the object should be placed between F (principal focus) and C (centre of curvature).

What is the position of image if magnification produced by a converging mirror is +3?

virtual and erect
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.

How do you find the magnification of a concave mirror?

1. The mirror formula is 1f=1v+1u.
2. The magnification m is given by m=−vu.
3. According to sign conventions, for a concave mirror, the focal length (f) is negative, the object distance (u) is negative, the image distance (v) is positive for a virtual image and negative for a real image.

What do you mean by magnification is 3 Brainly?

Answer: Magnification is the ratio of the height of the image to the height of the object. When we see a positive sign on the magnification then the image formed is virtual and erect. Explanation: hope it will help you if correct please mark me as brainliest.

Which mirror can produce magnification of +3?

Concave mirror
Concave mirror makes the object taller and wider because such mirrors are bent inward. d.) As magnification=-3, as we can see it is greater than one so the image is enlarged.

For which mirror magnification is always 1?

Answer Expert Verified The mirror must be a spherical mirror (concave mirror) as the magnification in plane mirror is never -1 but always 1. Also convex mirror always produces images smaller than the size of the object so it’s magnification is always less than 1.

Which mirror can produce magnification +3?

What is the nature of the image produced by a mirror if magnification is 3 also give the type of the mirror?

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.

In concave and convex mirrors, the magnification depends on the distance of the object from the mirror and the focal length. The mirror formula is 1 v + 1 u = 1 f, where u and v are the distances of the object and image from the mirror and f is the focal length. ⇒ 1 v = 1 f − 1 u = u − f u f.

What is the magnification of a plane mirror?

In a plane mirror the image is erect and of the same size as the object and hence the magnification is 1. In concave and convex mirrors, the magnification depends on the distance of the object from the mirror and the focal length.

What does a positive value of magnification indicate?

A POSITIVE SIGN in the value of magnification indicates that the image is a VIRTUAL IMAGE. If the value of magnification is GREATER THAN ‘1’ then the image formed is larger than the actual size of the object. If the value for magnification is LESSER THAN ‘1’ then the image formed is lesser than the actual size of the object.

What is the value of magmag of negative one?

Mag of negative one means that the image in INVERTED relative to the orientation of the object and EQUAL in height. This means that the image is REAL and equal in height to the object. It follows that the Di = Do. For a concave mirror, the condition that Di = Do with a REAL image occurs when Do is at (2 f); twice the focal length.
