Question

Calculate the de Brogile wavelength of a photon whose linear momentum has a magnitude of $3.3\times {10}^{-23}kgm/s$.

• A. 0.0002 nm
• B. 0.002 nm
• C. 0.02 nm
• D. 0.2 nm
• E. 2 nm

Answer 1

Answer: (C)

0.02 nm

The de Brogile wavelength of a photon is $\lambda =\frac{h}{p}=\frac{6.6\times {10}^{-34}}{3.3\times {10}^{-23}}=2\times {10}^{-11}=0.02\times {10}^{-9}m=0.02nm$
