Question 28.Q-Q.6: We have discussed two wavelengths associated with the electr...

(b). The Compton wavelength (Eq. 28.9) is a combination of constants and has no relation to the motion of the electron. The de Broglie wavelength (Eq. 28.10) is associated with the motion of the electron through its momentum.

\lambda_{ C }=\frac{h}{m_{e} c}=0.00243 nm                     [28.9]

\lambda=\frac{h}{p}=\frac{h}{m v}                     [28.10]
