## Wavelength Using Energy Solution

STEP 0: Pre-Calculation Summary
Formula Used
Wavelength = [hP]/sqrt(2*Mass*Energy in Electron Volts)
λ = [hP]/sqrt(2*M*E)
This formula uses 1 Constants, 1 Functions, 2 Variables
Constants Used
[hP] - Planck constant Value Taken As 6.626070040E-34 Kilogram Meter² / Second
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Mass - Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it. (Measured in Kilogram)
Energy in Electron Volts - Energy in Electron Volts is the energy consumed by the body when measured in electron volts. (Measured in Electron-Volt)
STEP 1: Convert Input(s) to Base Unit
Mass: 35.45 Kilogram --> 35.45 Kilogram No Conversion Required
Energy in Electron Volts: 45 Electron-Volt --> 7.20979798500003E-18 Joule (Check conversion here)
