Kinetic Energy in terms of threshold wavelength Solution

STEP 0: Pre-Calculation Summary
Formula Used
kinetic_energy = [hP]*[c]*(Threshold Wavelength-Wavelength)/(Wavelength*Threshold Wavelength)
KE = [hP]*[c]*(λo-λ)/(λ*λo)
This formula uses 2 Constants, 2 Variables
Constants Used
[c] - Light speed in vacuum Value Taken As 299792458.0 Meter/Second
[hP] - Planck constant Value Taken As 6.626070040E-34 kilogram Meter² / Second
Variables Used
Threshold Wavelength - Threshold wavelength is defined as the maximum wavelength that the incident radiation must have so that photoelectric effect takes place. (Measured in Angstrom)
Wavelength - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. (Measured in Nanometer)
STEP 1: Convert Input(s) to Base Unit

What is Kinetic energy?

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

What is Photo-electric effect?

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons.
