High-Energy Cancer Treatment.
Scientists are working on a new technique
to kill cancer cells by zapping them
with ultrahigh-energy (in the range of
1012 W) pulses of light that last for an
extremely short time (a few nanoseconds).
These short pulses scramble the interior
of a cell without causing it to explode, as
long pulses would do. We can model a
typical such cell as a disk in 3 mm
diameter, with the pulse lasting for 7 ns
with an average power of 7.4 x10¹2 W.
We shall assume that the energy is spread
uniformly over the faces of 100 cells for
each pulse. How much energy is given to
the cell during this pulse?
(answer in 2 decimal places and in
MegaJoule (MJ))
m, = 4px 107T. m/ A
c = 3 x 108 m/s

Roughly what frequency and what kind of light would you need to be able to
separate an electron from a proton?
Of = 1018 H z, x ray
f = 1014 H z, visible light
Of = 102° H z, y ray
O f = 10° H z, microwave
