The image formed by a concave mirror is observed to be virtual, erect and larger than the object Where should be the position of the object? [NCERT]
(a) Between principal focus and centre of curvature
(b) At centre of curvature
(c) Beyond centre of curvature
(d) Between pole of the mirror and its principal focus
Answers
Answer:
between the pole of the mirror and its principal focus
Answer:
Between the pole of the mirror and its principal focus. [Option D]
Reason:
The image formed by a concave mirror, When an object placed between the pole of the mirror and its principal focus eract, virtual, larger and magnified image will be formed.
Additional information:
\bf{ Concave \: mirror :}Concavemirror: It is the spherical mirror with outwards curved reflecting surface.
Uses of concavemirror:
Concave mirrors are used in vehicles, torches and in headlights.
Concave mirrors are used by dentist to see large image of the patient's teeth.
Concave mirrors are used in base of a microscope.
Concave mirrors are used in shaving mirrors of salon to see large image of the face.
Concave mirrors are also used in medical field. It is used in instruments such as ophthalmoscope and otoscope.
Formation of image:
If the position of object is at infinity and position of image is at focus, the formation of the image will be real and inverted.
If the position of object is at the focus and the image is at infinity, the real, inverted and extremely magnified image will be formed.
If the position of an object is between the pole and at focus and the position of image is behind the mirror, then the virtual, erect and magnified image will be formed.
