The correct answer should be C
according to the explantion given by myschool
F1/F2= √T1/2T1
T1 will cancel out leaving 1/2
F1/F2 =√1/√2
F1/F2 = 1/√2
now in order to find the ratio of the new frequency to the initial frequency we need the inverse which will now be
F2/F1 =√2/1
F2/F1 =√2

the answer should be √2......cos F1:F2 is 1:√2......when you inverse it, you get √2 (C) @myschool

I was actually confused, i had to check my workings again
The answee should be √2
