Question

If the frequency of an FM wave is 8.85 × 10¥ hertz, what is the period of the FM wave?

Answer 1

The value of the period of the wave is the reciprocal of its frequency in hertz (1/s). From the given above, the value of the period is calculated below,
                                 t = 1 / f = 1 / (8.85 x 10^7 1/s)
Thus, the value of period (t) is equal to 1.13 x 10^-8 s. The answer is letter B. 

Answer 2

for plato users it is 1.10 X 10^-8 just took the test got 100 percent so ik its right
