Que. Given two sine waves A and B, if the frequency of A is twice that of B, then the period of B is ________ that of A.
a. one-half
b. twice
c. the same as
d. indeterminate from
Answer:twice
Raj :(November 30, 2018) A=2B in f
Time will be one half of 8right
How it is twice? Pls prove it

Ailis :(February 24, 2020) f(A)= 2*f(B)
1/T(A)=2*[1/T(B)]
T(A)=T(B)/2
THEREFORE, T(B)= 2T(A)
