Explain how a charged amber rod can lift tiny bits of paper despite being under the gravitational force of the entire mass of the earth.

The de Broglie relation λ=h/p can be rewritten in terms of the wave number k as p=kℏ. Recall that wave number is defined by k=2π/λ. Using the fact that λ=v/f, find the wave numbers k1 and k2 corresponding to frequencies f1 and f2.
