In Periodic Functions, What is the difference between Periodicity & Fundamental period? ( I mean, when question asks to find periodicity, we find only the fundamental period right?)

Step-by-step explanation:
The time interval between two waves is known as a Period whereas a function that repeats its values at regular intervals or periods is known as a Periodic Function. In other words, a periodic function is a function that repeats its values after every particular interval.
The period of the function is this particular interval mentioned above.
A function f will be periodic with period m, so if we have
f (a + m) = f (a), For every m > 0.
It shows that the function f(a) possesses the same values after an interval of “m”. One can say that after every interval of “m” the function f repeats all its values.
For example – The sine function i.e. sin a has a period 2 π because 2 π is the smallest number for which sin (a + 2π) = sin a, for all a.
