Hey matethe correct answer must be convex if i helped plzz mark me as brainliest
The mirror used is concave.
The formula for finding magnification of a mirror is given as:
Magnification = height of image/height of object
A magnification of +1.5 signifies an image with the following characteristics:
3. Erect and upright
This is possible when the object is placed between the focus and the centre of the mirror.
The image, in this case, is formed behind the mirror.
Positive magnification suggests that image formed is virtual, erect and enlarged.
Thus, only concave mirror can produce such an image. when the object is placed between pole and focus, a virtual, erect and magnified image is produced behind the mirror.
Plane mirror produces virtual image but of the same size as of object. Convex mirror always forms virtual erect but diminished image.
convex is the answer
It is a concave mirror.
Magnification(M) can be determined as:
M = Image height/ Object height
Also, M = - v/u , where v= image distance and u is object distance.
As per convention, if the image formed is inverted then the height of the image will be negative.
Therefore, for magnification to be positive the height of the image needs to be positive , which means that the image formed is erect and also virtual.
This is possible only in case of a concave mirror in which the object is placed inside the focal length, thereby producing an enlarged, erect and virtual image behind the mirror.
concave mirror as image is larger than the object
It's convex lens
It is an concave mirror.
Because, if the magnification is positive, then the image is virtual and erect.
And if the magnification is more than 1, the image is enlarged.
This case is only formed by a concave mirror when the object is in between pole and focal point.
the magnification is +1.5
here +sign indicates that the mirror is convex .
so it is a convex mirror.
this may help you...
make the ans in brain list..
