Question

nature , position of the image and type of lens used when magnification is (-1)​

Answer 1

Answer:

Magnification is negative so image is real and inverted. The picture is shaped 100 cm behind the mirror. Magnification is negative, meaning that the image is real and is inverted.

Answer 2

Answer:

Image is same size of the object, real , inverted and the lens is concave lens.

Step-by-step explanation:

Explanation:

Given in the question, magnification of lens = -1

• Magnification is calculated as follows:

$\frac{height \ of \ the \ image}{height \ of \ the \ object}$  = $\frac{h_1}{h_2}$ = -1

• Positive magnification denotes virtual and erect, while negative magnification implies that the image is real and inverted.

• Magnification is a metaphor for the size of the created image.

• -1 magnification indicates that the image created is the same size as the object.

• Since, the magnification in a plane mirror is never -1 but always 1, the mirror must be spherical (concave).

• Additionally, a convex mirror's magnification is always less than one since it always creates pictures that are smaller than the object.

• It is therefore a concave mirror.

• Therefore, the image must match the object's size exactly.

• Because of the negative magnification, it is possible to obtain an real, inverted image on the screen.
