Problem 4.212

Find the mean radiation power of an electron performing harmonic oscillations with amplitude a=0.10nma=0.10 \mathrm{nm} and frequen cy ω=6.5⋅1014 s−1\omega=6.5 \cdot 10^{14} \mathrm{~s}^{-1}

Reveal Answer
⟨P⟩=14πε0e2a2ω43c3=5⋅10−15 W\langle P\rangle=\frac{1}{4 \pi \varepsilon_{0}} \frac{e^{2} a^{2} \omega^{4}}{3 c^{3}}=5 \cdot 10^{-15} \mathrm{~W}
