# When the image is negative, what will the mirror be?

The negative value for magnification and picture height indicates that the image is inverted in relation to the object. To conclude, the picture is genuine, inverted, 6.2 cm tall, and 17.7 cm in front of the mirror. The mirror does not reflect any parts of the image.

## When is the magnification of a mirror negative when the magnification of a mirror is negative?

In a concave mirror, magnification is negative. The magnification of a concave mirror is determined by the ratio of the image's height to the object's height. As a result, the magnification will be negative if the picture is inverted and actual. If you look into a mirror that has been painted black, you can see how negative magnification works. Because of this property, concave mirrors have many useful applications. For example, they can be used for viewing objects that are too far away from be seen with normal vision or as telescopes for observing faraway objects such as planets or galaxies.

Convex mirrors do not invert images but they do exhibit negative magnification. Just like concave mirrors, convex mirrors can be used for viewing objects that are too far away or as telescopes. However, because of the negative magnification, objects that are closer to the lens appear larger than they actually are.

The magnification of a mirror is the factor by which the image size on the screen/paper/whatever is assumed to be multiplied to get the actual size of the image. So, if we take an example where the image size on the screen is 10 inches tall and we want to know what its actual height would be, we just divide the image height by the magnification of the mirror to get the actual height. In other words, 10 inches / 1.5 = 6.66 feet.

## Do real images have negative magnification?

Magnification is defined as the ratio of the image's height to the object's height. In the event of an actual picture, the image is inverted, thus the image's height has a negative sign, whilst the object's height has a positive value. The magnification is minuscule. For example, if you were to magnify a penny 1:1000, it would be invisible.

In science class, we are often asked to calculate the magnification of a microscope or telescope lens. Magnification can also be used as a term for describing how much larger or smaller an object is compared to its original size. For example, if you looked at an apple under a microscope, that would be considered microscopic viewing because even though you are looking at something very small, it is still quite large compared to what you are actually seeing. In this case, the apple is being magnified many times over when viewed with a microscope.

When calculating the magnification of an optical system, such as a microscope lens, it is important to remember that the image becomes smaller relative to the object. Thus, when calculating the magnification, you should divide the final image height by the initial object height to obtain the true magnification.

For example, if you were to look at an object under a microscope and saw that one side was 100 microns tall and the other side was 10 microns tall, then the magnification would be 10,000 since 1000 microns is one millimeter.
