Einstein S Photoelectric Equation Energy Quantum Of Radiation

Step 1: Write the de Broglie relation.

%5Clambda%20%3D%20%5Cfrac%7Bh%7D%7Bmv%7D

Step 2: Substitute values.

h%20%3D%206.626%20%5Ctimes%2010%5E%7B-34%7D~%5Ctext%7Bm%7D%5E2%5Ctext%7Bkg%2Fs%7D%2C%20%5Cquad%20m%20%3D%201.67%20%5Ctimes%2010%5E%7B-27%7D~%5Ctext%7Bkg%7D%2C%20%5Cquad%20v%20%3D%201.0~%5Ctext%7Bm%2Fs%7D

%5Clambda%20%3D%20%5Cfrac%7B6.626%20%5Ctimes%2010%5E%7B-34%7D%7D%7B1.67%20%5Ctimes%2010%5E%7B-27%7D%20%5Ctimes%201.0%7D%20%3D%203.97%20%5Ctimes%2010%5E%7B-7%7D~%5Ctext%7Bm%7D

Step 3: Convert meters to Ångström.

1~%5Ctext%7B%C3%85%7D%20%3D%2010%5E%7B-10%7D~%5Ctext%7Bm%7D%20%5CRightarrow%203.97%20%5Ctimes%2010%5E%7B-7%7D~%5Ctext%7Bm%7D%20%3D%203.97%20%5Ctimes%2010%5E%7B3%7D~%5Ctext%7B%C3%85%7D

Wait — check unit consistency carefully:

3.97%20%5Ctimes%2010%5E%7B-7%7D~%5Ctext%7Bm%7D%20%3D%203.97%20%5Ctimes%2010%5E%7B3%7D~%5Ctext%7B%C3%85%7D

Final Answer: 3.97 × 10 $%5E%7B3%3C%2Fstrong%3E$ Å}

Step 4: Conclusion.
The de Broglie wavelength = 3.97 × 10 $%5E%7B3%3C%2Fstrong%3E$ Å}.
