Just hoping you might explain the physics here for me.(adsbygoogle = window.adsbygoogle || []).push({});

An electron is placed in an oscillating electric field, say,

[tex]E = E_0\sin(\omega t)[/tex]

and as a result accelerates in x at,

[tex]a = a_0\sin(\omega t)[/tex]

(grouped some constants in a_0). Solving for the resulting motion yields,

[tex] x = \frac{a_0}{\omega}t - \frac{a_0}{{\omega}^2}\sin(\omega t) [/tex]

In the second term we see the expected oscillatory motion. However, in the first term we have something corresponding to uniform velocity! The electron drifts as well as oscillates!

Why?

Thanks
