The nature of an image formed by a concave mirror when an object is kept at the position between the principal focus and the pole of the mirror is ________.
virtual and inverted
real and inverted
real and erect
virtual and erect
virtual and erect
When an object is placed between the principal focus (F) and the pole (P) of a concave mirror, the reflected rays diverge. When these rays are extended backwards behind the mirror, they appear to meet, forming an image that is virtual, erect, and magnified.
When an object is placed between the principal focus (F) and the pole (P) of a concave mirror, the reflected rays diverge. When these rays are extended backwards behind the mirror, they appear to meet, forming an image that is virtual, erect, and magnified.
This is the exact principle behind a shaving mirror or makeup mirror. When you bring your face very close to the mirror (closer than the focal point), you see a magnified, right-side-up (erect) image of your face behind the mirror.
Remember 'P-F-V': Pole to Focus yields Virtual (and erect, magnified).

m=тИТuvтАЛ=hoтАЛhiтАЛтАЛ тАФ Magnification Formula
A concave mirror converges light rays. However, when the object distance u is less than the focal length f (u<f), the incident rays from the object strike the mirror such that the reflected rays diverge away from each other. Since they never actually intersect in front of the mirror, an observer looking into the mirror sees them diverging from a point behind the mirror, resulting in a virtual image which is erect and larger than the object.
When an object is placed between the pole (P) and principal focus (F) of a concave mirror, the image formed is virtual and erect.
Unlike all other positions where concave mirrors form real and inverted images, this specific position produces a magnified virtual image behind the mirror.
Magnification (m) is positive and greater than 1 (m>1).
Used in shaving mirrors, makeup mirrors, and ophthalmoscopes.
Provides a magnified and upright view of the object, which is helpful for close-up viewing tasks.
Image cannot be projected onto a screen since it is virtual.
Shaving and makeup mirrors
Dentist's head mirrors to examine teeth
Ophthalmoscopes used by doctors to examine eyes
Option A (virtual and inverted) is incorrect because virtual images formed by mirrors are always erect.
Option B (real and inverted) occurs when the object is placed beyond the focus (u>f).
Option C
