# What is the formula for converging lens?

## What is the formula for converging lens?

Ans. According to the convex lens equation, 1/f = 1/v + 1/u. It relates the focal length of a lens with the distance of an object placed in front of it and the image formed of that object.

## What is the magnification formula of lens?

Let’s explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it’s real or virtual).

**What is the fundamental lens equation?**

The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = – distance of the image over distance of the object. Remember that the focus is on the proper side of a lens when it’s converging.

### What is the lens equation used for?

The lens equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f).

### How is the Curie law related to the temperature?

The curie law states that the material’s magnetization is directly proportional to an applied magnetic field in a paramagnetic material. Mathematically, it is written as B is the magnetic field. T is the absolute temperature. C is a material-specific Curie constant. Let us understand some terms to understand curie law better:

**How is the Curie Weiss law related to magnetic susceptibility?**

The Curie Temperature is an essential topic when it comes to the JEE Mains Syllabus. Magnetic susceptibility is inversely proportional to the absolute temperature T. The magnetization in a paramagnetic material is directly proportional to the applied magnetic field. The Curie Weiss law is applicable only above T c.

## What is the formula for Curie’s law of magnetization?

The formula above is known as the Langevin paramagnetic equation . Pierre Curie found an approximation to this law that applies to the relatively high temperatures and low magnetic fields used in his experiments. Let’s see what happens to the magnetization as we specialize it to large .

## Which is a modified version of Curie’s law?

The Curie-Weiss Law is a modified version of Curie’s Law, which for a paramagnetic material may be written as Where µ0 is the permeability of free space; M the magnetization (magnetic moment per unit volume), B=µ0H is the magnetic field, and C the material-specific Curie constant.
