NEET Physics Time Period & Frequency Assertion Reason Question
Assertion (A): The function f(t) = A sin ωt has a period T. | Reason (R): A linear combination of sine and cosine functions is always a non-periodic function.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true as f(t) = A sin ωt is periodic with period T. The reason is false because a linear combination of sine and cosine functions like f(t) = A sin ωt + B cos ωt is also periodic.
