Answer Posted / nahin
yes.
fluorescent bulb works under the principle of scattering of
electron.An incident electron collides with an atom in the
gas. According to the Einstein formula: Kmax=hf+phi,
the kinetic energy depends on the frequency. So, if we
reduce the frequency, the kinetic energy of electrons will
also be reduced and thus the performance will be degraded.
