Question

What do you know about lens formula and magnification​

Answer 1

Answer:

Lens formula:

The greater effect a lens has on light rays, the more powerful it is said to be. A powerful converging lens will focus parallel light rays closer to itself and will have a smaller focal length than a weak lens. The power of a lens is given by the equation P=1f P = 1 f .

Magnification formula:

The magnification equation states that M = Hi/Ho = - Di/Do, where M is the magnification, Hi is the height of the image, Ho is the height of the object, Di is the distance from the lens to the image and Do is the distance of the object to the lens. The minus sign signifies the fact that the image will be inverted.

What do you mean by lens formula ?

In optics, the relationship between the distance of an image (v), the distance of an object (u), and the focal length (f) of the lens is given by the formula known as Lens formula.

Lens formula:-

(1/v-1/u= 1/f)

Magnification:-

The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object. Furthermore, the letter 'm' denotes the magnification of the object. Besides, its formula is: Magnification (m) = h / h' Here, h is the height of the object and h' is the height of the object.
