Locating Object & Image with a Converging Lens

In summary, a converging lens with a focal length of 7 cm forms an image that is 1.10 cm tall and erect when a 4 mm tall real object is placed to the left of the lens. The object is located at a distance of -31 cm (to the left) and the image is located at a distance of 7 cm (to the right). Similarly, a converging lens with a focal length of 12 cm forms a virtual image that is 5 mm tall and located 19 cm to the right of the lens. Using the lens equation and linear magnification formula, the position of the object can be determined to be 30 cm (to the left) and the size

1) Aconverging lens with a focal length of 7 cm forms an image of a 4 mm tall real object that is to the left of the lens. The image 1.10 cm tall and erect.
Where is the object located?
Where is the image located?
2) A converging lens with a focal length of 12 cm forms a virtual image 5 mm tall, 19 cm to the right of the lens.
Determine the position of the object. (Give the object distance with the correct sign).
Determine the size of the object.

You'll need the lens equation: 1/f = 1/o + 1/i, and the definition of linear magnification: m = -i/o.

Look up how these equations are used and give the problems a try.

There is a good simulation program picture what about it

What is a converging lens?

A converging lens, also known as a convex lens, is a curved piece of glass or other transparent material that is thicker in the middle and thinner at the edges. It is able to bend and focus light rays that pass through it to converge at a single point, known as the focal point.

How does a converging lens locate objects and images?

A converging lens uses its curved shape and ability to bend light to locate objects and create images. When an object is placed in front of a converging lens, the lens refracts the light rays from the object and focuses them at a point behind the lens. This point is where the image of the object appears.

What factors affect the location of an object or image with a converging lens?

The location of an object or image with a converging lens is affected by three main factors: the distance of the object from the lens, the focal length of the lens, and the distance of the image from the lens. These factors determine the magnification and orientation of the image.

How do you calculate the location of an object or image with a converging lens?

The location of an object or image with a converging lens can be calculated using the thin lens equation: 1/o + 1/i = 1/f, where o is the object distance, i is the image distance, and f is the focal length of the lens. This equation takes into account the three factors that affect the location of an object or image.

What are some real-life applications of locating objects and images with a converging lens?

Converging lenses are used in various applications such as eyeglasses, microscopes, telescopes, and cameras. They are also used in optical devices for correcting vision, such as contact lenses and intraocular lenses. In addition, they are used in scientific research and experiments for magnifying and studying small objects and images.
