Yes FT of impulse is DC signal i.e., in frequency domain
amplitude is constant for all frequencies(sketch the DC
signal with independent variable as frequency)....so it has
infinite frequencies....FT of impulse is DC signal but
impulse is not DC signal as it will not exist for all
time...
If impulse is a DC signal then we can say that its
frequecy is zero...but clearly impulse is not a DC signal
(time domain)...
