An atom in a crystal vibrates with s.h.m. with a frequency of ${10}^{14} \mathrm{Hz}$. The amplitude of its motion is $2.0\times {10}^{-12} \mathrm{m}$

Sketch a graph to show how the displacement of the atom varies during one cycle.

An atom in a crystal vibrates with s.h.m. with a frequency of ${10}^{14} \mathrm{Hz}$. The amplitude of its motion is $2.0\times {10}^{-12} \mathrm{m}$. Use the graph to estimate the maximum velocity of the atom.
