How to find the magnification of a lens?

To find the magnification of a lens, you can use the formula: Magnification image height / object height. This formula compares the size of the image produced by the lens to the size of the original object. The magnification value will tell you how much larger or smaller the image appears compared to the object.


A change in the size of an image compared with the size of an object?

The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.


What is the magnification of a real image of the image is 10.0 cm from a mirror and the object is 50.0 cm from the mirror?

The magnification formula for a mirror is given by M = -di/do, where di is the image distance and do is the object distance. Substituting the given values, we find M = -10.0 cm / 50.0 cm = -0.2. Thus, the magnification of the real image is -0.2.


What do positive and negative sign of magnification indicate?

Positive would be more magnification, and negative would be less magnification. * * * * * No. M > 1 indicates that the image is bigger than the pre-image (and on the same side of the centre of magnification); 0 < M < 1 indicates that the image is smaller than the pre-image (and on the same side of the centre of magnification); -1 < M < 0 indicates that the image is smaller than the pre-image (and on the opposite side of the centre of magnification); M < -1 indicates that the image is larger than the pre-image (and on the opposite side of the centre of magnification). M = 0 means the image is point-sized and at the centre of magnification. M = 1 means the image coincides with the pre-image. M = -1 means that the image is the same size as the pre-image and on the opposite side.


With what magnification do you see the brightest image?

The image appears brightest at 1x magnification, which means viewing the object at its true size without any magnification.


Formula for finding the magnification of a cell?

The magnification of a cell can be calculated using the formula: Magnification = Image size / Real size. This formula compares the size of the image of the cell to its actual size in order to determine the level of magnification.


What is the magnification of a virtual image if the image is 60.0 cm from a mirror and the objects is 15.0 cm from the mirror?

The magnification of the virtual image is 4.0. This is calculated by dividing the image distance by the object distance: 60 cm (image distance) / 15 cm (object distance) = 4.0 magnification.


What does negative sign if the value of magnification of a mirror indicate?

It means that the pre-image and image are on opposite sides of the centre of magnification.


What is the Magnification equation for concave mirror?

The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.


Magnification and resolution as they pertain to a microscope?

Magnification lets you see an image larger than it is. But resolution makes the image clearer when magnified.


Why are today microscope called compound scopes?

Because the magnification of image = magnification of eyes piece * magnification of lens.


What is the magnification of a microscope with two lenses that each enlarged an image by 10x?

The total magnification would be 100x. This is because when two lenses are used together, the magnification of each lens is multiplied to find the total magnification. So, 10x magnification from the first lens multiplied by 10x magnification from the second lens gives a total magnification of 100x.
