The Fourier transform of a function f (x) is defined as:
f (w) = L dx
f (ω) -.
f (x)e-iwx
Similarly, the inverse Fourier transform of a function
f (w) whose Fourier transform is known is found as:
1
f(x) = L f (w) e-iwx dw
So, find the Fourier transform f (w) for a> 0 of the
function given below, and using this result, calculate the
inverse Fourier transform to verify the form f (x) given to
you:

Scientists are working on a new technique to kill cancer cells by zapping them
with ultrahigh-energy (in the range of 1.00×1012 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 5.00 μm in diameter, with the pulse lasting
for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the
energy is spread uniformly over the faces of 100 cells for each pulse.
