Answer 2

Answer:

Answer no.1:-

As per the question, the magnigication of the mirror is -ve.

• Since the magnification of concave mirror is always negative, it indicates that the type of mirror is concave.

Answer no.2:-

• Concave mirrors may create both real and virtual image.
• They can also be enlarged, diminished, or the same size as the object.
• They can be upright (if virtual) or inverted (if real); in front of the mirror (if real); or behind the mirror (if virtual).

This is because there is a link between object distance and object size, as well as image distance and image size. Starting with a large value, the distance between the object and the mirror decreases as the object is brought closer to the mirror, increasing the image distance, while the image height increases.

Answer no.3:-

Given:

Magnification - -1.25

Size of the object = 2 cm

So, magnification = size of image/ size of object

Size of image = Magnification × Size of object

Size of image = -1.25  × 2

∴ Size of image = -2.50 cm

Answer no.4:-

The object can either be positioned at Focus or between Focus and Centre of curvature.
