Magnification is defined as ratio of height of image to the ratio of height of object. It is a concave mirror which has magnification denoted by the sign minus. Nature of the mirror is
real and inverted
.
What is the nature of mirror if magnification is negative?
Negative magnification means that the image formed by a spherical mirror
is real and inverted
.
What is the nature of the mirror if the magnification is?
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.
Which mirror gives magnification of +1?
concave mirror
gives a magnification of -1.
What is the nature of the image if magnification is 1?
The magnification of a mirror is -1. Hence, the image formed is
real and inverted
.
Is magnification positive for real image?
The question is a very common one. Magnification is the ratio between the height of the object and the height of the image. In the case of a real image,
the height of the object carries a positive sign
while the height of the image carries a negative one. Hence the magnification is negative.
What if the magnification is positive?
Magnification can be defined as the ratio of size of the image to the size of the object. … If the ratio is positive then
the image is virtual and erect
. So, according to these sigh conventions, when the magnification is positive then the image has to be erect and virtual.
Is magnification positive or negative?
Magnification: The ratio of the height of the image to the height of the object is called the magnification of the spherical mirror. The
magnification of the actual image will always be negative
and the virtual image should always be positive.
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.
What information does the magnification by a mirror gives about the size and nature of the image?
Magnification =
height of the image/height of the object = distance of the image/distance of the object
. The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object.
What happens when magnification is 1?
Magnification. … 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.
Which lens has 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 mirror has real focus?
A concave mirror reflecting surface is bent inward to focus, i.e., away from the light source. When the curve bounces the light up to a particular area, they form an image. It is true that a convex mirror has virtual focus or
a concave mirror
has real focus.
What is the nature of the image if the magnification has positive value?
a -ve magnification corresponds to a real,inverted image; while positive magnifiaction corresponds to a
virtual , erect image
.
How magnification can represent the nature of image?
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called “magnification”. … In all cases, the magnification of
the image does not change the perspective of the image
.
Which mirror the magnification is always same?
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.
