Question

prove that product of ferquency and rime period is unity

Answer 1

Answer:

Seeing that time is the reciprocal of frequency (T=1/f) simple algebra will show that 1=T x f.

So 1 is a product of frequency and time.

What’s curious is this: regulated or otherwise well filtered direct current (DC) is also known as 0 Hz. By definition, that would mean that there is also no period. So that would mean that 0/0=1, although there are those that would argue that anything divided by zero (even zero) is undefined.

Answer 2

Answer:

by the definition, the period 'T' of an oscillating phenomenon is the reciprocal of its frequency f'
