Magnification is negative in a **concave mirror**.

In which mirror magnification is positive? Magnification of a **convex mirror** is always positive, but that of a concave mirror may be both positive or negative.

Simply so What happens if the magnification is less than 1?

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**.

Likewise, What if magnification is less than 1? Magnification refers to a change in size of the object. If the magnification is greater than one, the image is larger than the object, but if the magnification is smaller than one the image is smaller than the object. … If the sign is positive, then the image is **upright**.

## In which case magnification is less than 1?

Magnification less than 1 means that image formed is smaller than the size of the object. This is possible in cases of **Convex mirror or Concave lens**.

**What if magnification is less than 1?**

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.

**In which mirror magnification is positive and less than 1?**

Hint The **convex mirror** always produces images of smaller size than the size of object. So, the value of magnification is always less than 1. For the concave mirror, the value of magnification is greater than 1. In the plane mirror, the magnification value is equal to 1.

**Which mirror can produce magnification of 3?**

**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.

**What type of mirror is it when the magnification is less than 1?**

Also convex mirror always produces images smaller than the size of the object so it’s magnification is always less than 1. Hence it is a **concave mirror**.

**Can magnification of concave mirror be less than 1?**

The image formed by a concave mirror is always smaller than the size of the object. Therefore, the magnification of a concave mirror is **always less than 1**.

**Does negative magnification mean smaller image?**

A magnification of 1 (plus or minus) means that the image is the same size as the object. … If the magnification is positive, the image is upright compared to the object; **if m is negative, the image is inverted compared to the object**.

**What is magnification class 10th?**

Magnification is defined as **the enlargement of the image formed by a mirror**, whether it is a concave mirror or a convex mirror, relative to the size of the object. … The mirror which can give an erect and enlarged image of an object is a concave mirror.

**What is the magnification Formula 1?**

**Magnification (m) = h/h’**

And h’ is the image height and h is the object height.

**What is the magnification formula?**

The magnification equation states that **M = Hi/Ho = – Di/Do**, where M is the magnification, Hi is the height of the image, Ho is the height of the object, Di is the distance from the lens to the image and Do is the distance of the object to the lens.

**In which mirror magnification is greater than 1?**

In **a concave mirror**, when the distance of the object is less than the focal length, the magnification will be greater than one.

**What is negative magnification?**

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.

**What does it mean if magnification is 0?**

a image with zero magnification is **the image which is not formed**… an image is formed by the intersection of multiple light rays so the magnification could be 0.0000000000000000ⁿ00001 or even lesser than this but complete zero means image is not formed.

**Why is the magnification of a plane mirror 1?**

**The distance of object and distance of image are equal in the case of a plane mirror and the object distance is negative**. Which gives us a magnification of +1.

**How do you know if an image is erect or inverted?**

When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and **inverted**. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright. A negative m means that the image is inverted. Positive means an upright image.

**What is magnification of a mirror Class 10?**

Magnification is defined as **the enlargement of the image formed by a mirror**, whether it is a concave mirror or a convex mirror, relative to the size of the object. The physical size of an object does not change, rather the size of the image changes.

**What is the magnification of convex mirror?**

As the object will get closer to the mirror the image will get bigger and bigger but it will not get bigger than the original object. So, the image formed in a convex mirror is always virtual and diminished. So, the magnification of a convex mirror is **always less than 1**.

**What is the magnification of concave mirror?**

In a concave mirror, when the distance of the object is less than the focal length, the **magnification will be greater than one**. When the distance of the object is greater than the focal length, then the magnification is less than one.

**What is magnification Vedantu?**

Magnification can be defined with the height of the image as well as the distance of the object. It is **the ratio between height of object and height of image**. It is denoted by “m” in the mathematical formula.

**What is meant by magnification Class 9?**

Magnification is defined as **the ratio of height of the image to the height of the object**. It tells us the amount by which the object is magnified with respect to the object.

**What is magnification Class 9?**

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.
