Photon's Energy using Wavelength Solution

Follow our step by step solution on how to calculate Photon's Energy using Wavelength?

FIRST Step Consider the formula

E = \frac{[hP] \cdot [c]}{λ}

Next Step Substitute values of Variables

∴

E = \frac{[hP] \cdot [c]}{2.1nm}

Next Step Substitute values of Constants

∴

E = \frac{6.6E-34 \cdot 3E+8m/s}{2.1nm}

Next Step Convert Units

∴

E = \frac{6.6E-34 \cdot 3E+8m/s}{2.1E-9m}

Next Step Prepare to Evaluate

∴

E = \frac{6.6E-34 \cdot 3E+8}{2.1E-9}

Next Step Evaluate

∴

E = 9.45926582938932E-17J

LAST Step Rounding Answer

∴

E = 9.5E-17J
