Between which two points of a concave mirror should an object be placed to obtain a magnification of 32?
1)when the object is kept between the pole and the focus of the concave mirror in front of it. the image formed will be virtual,erect and magnified. 2)when the image us kept between the focus and the center of curvature.
Between which two points of a concave mirror should an object be placed to obtain an image on a screen twice the size of the object?
Answer: To obtain an image twice the size of the object, we must place it between F (focus) and P (pole) of the mirror, or between C (centre of curvature) and F (focus).
Between which two points of a concave mirror should an?
The object must be placed between the pole and the principal focus (F) of the concave mirror.
Which two points of a concave mirror should an object be placed?
Between which two points of a concave mirror should an object be placed to obtain a magnification of -3? A magnification of -3 means that the image is real, inverted and magnified. So the object should be placed between F (principal focus) and C (centre of curvature).
What is the meaning of negative sign in concave mirror?
Answer: When the object is placed between the Centre of curvature and Principle Focus of the concave mirror, them the image formed is magnified and real (hence the negative sign) and is formed beyond the Centre of curvature on the same side where the object is placed.
Where should the object be placed to obtain magnification of +25?
So the object should be placed between F (principal focus) and C (center of curvature). For (b) An object, in front of a concave mirror, should be placedbetween the latter’s focus (F) and the pole (P) to obtain a magnification of +25.
What happens to the image formed when a mirror is reflected?
These rays after reflection converge and form an image at F, the principal focus of the mirror, in front of the mirror. The image thus formed is highly diminished, point size, real and inverted. In this situation we consider two different rays emerging from the object.
