## How do you write an equation for spherical coordinates?

To convert a point from spherical coordinates to cylindrical coordinates, use equations r=ρsinφ,θ=θ, and z=ρcosφ. To convert a point from cylindrical coordinates to spherical coordinates, use equations ρ=√r2+z2,θ=θ, and φ=arccos(z√r2+z2).

## What is the equation of a sphere in spherical coordinates?

A sphere that has the Cartesian equation x2 + y2 + z2 = c2 has the simple equation r = c in spherical coordinates.

What is Schrodinger wave equation in spherical polar coordinates?

If the potential energy and the boundary conditions are spherically symmetric, it is useful to transform H into spherical coordinates and seek solutions to Schrödinger’s equation which can be written as the product of a radial portion and an angular portion: ψ(r, θ, φ) = R(r)Y (θ, φ), or even R(r)Θ(θ)Φ(φ).

E = E1 + E2 + E3. One can now substitute these expressions into the full 3D Schrodinger equation and see that they solve it even at the points r where ψ(r) = 0. Therefore, the solution of the 3D Schrodinger equation is obtained by multiplying the solutions of the three 1D Schrodinger equations.

### What is the equation for a sphere?

Answer: The equation of a sphere in standard form is x2 + y2 + z2 = r2. Let us see how is it derived. Explanation: Let A (a, b, c) be a fixed point in the space, r be a positive real number and P (x, y, z ) be a moving point such that AP = r is a constant.

### How do you write a sphere in cylindrical coordinates?

1. x2+y2+z2=R2 .
2. Since x2+y2=r2 in cylindrical coordinates, an equation of the same sphere in cylindrical coordinates can be written as.
3. r2+z2=R2 .

Why spherical polar coordinates are used in Schrödinger equation?

Question: Spherical polar coordinates are used in the solution of the hydrogen atom Schrödinger equation because the Laplacian operator has its simplest form in spherical polar coordinates. cartesian coordinates would give particle-in-a-box wavefunctions.

Which of the following equation is the Schrödinger wave equation for hydrogen atom in polar coordinates?

Ψ2s=42 π1(a01)3/2[2−a0r0]e−r/a0. where a0 is Bohr radius.

#### What is meant by Schrodinger wave equation?

Schrodinger wave equation is a mathematical expression describing the energy and position of the electron in space and time, taking into account the matter wave nature of the electron inside an atom.

#### What is the difference between cylindrical and spherical coordinates?

In the cylindrical coordinate system, location of a point in space is described using two distances ( r and z ) ( r and z ) and an angle measure. ( θ ) . In the spherical coordinate system, we again use an ordered triple to describe the location of a point in space.
