Work Function and Kinetic Energy Calculator
Here’s a JavaScript-bas calculator that allows you to calculate the kinetic energy of eject electrons bas on the work function of a material and the frequency or wavelength of incident light:

JavaScript

function calculateKineticEnergy(workFunction, frequency) {
const h = 6.626e-34; // Planck’s constant (J*s)
const kineticEnergy = h * frequency – workFunction;
return kineticEnergy;
function calculateFrequencyFromWavelength(wavelength) {
const c = 3e8; // Spe of light (m/s)
return c / wavelength;

 Example usage:

const Europe Cell Phone Number List workFunction = 2.3; // eV (convert to Joules if ne)
const wavelength = 400; // nm (convert to meters if ne)

 

Use code with caution.

Explanation:

calculateKineticEnergy Phone Number Digital Library function:

Takes the work function (in Joules) and frequency as input.

Calculates the kinetic energy using the equation KE

The work function is typically TWD Directory given in electron volts (eV). You ne to convert it to Joules for calculations.
The wavelength is usually given in nanometers (nm). You ne to convert it to meters for calculations.
You can customize this code further by:

Adding a user interface (e.g., HTML and JavaScript) to allow users to input values

Incorporating error handling for invalid inputs.

Expanding the functionality

A handle different units or calculations.
