Question

If the frequency of an FM wave is 8.85 × 107 hertz, what is the period of the FM wave?

Answer 1

Answer: The period of the FM wave $1.1299\times 10^{-8} seconds$.

Explanation:

Frequency of the wave = $8.85\times 10^{7} Hertz$

Frequency is inverse of time period that is :

$Frequency=\frac{1}{\text{Time period}}$

$\text{time period}=\frac{1}{frequency}$

$=\frac{1}{8.85\times 10^{7} Hertz}=0.11299\times 10^{-7} seconds=1.1299\times 10^{-8} seconds$

The period of the FM wave $1.1299\times 10^{-8} seconds$.

Answer 2

NAMASTE

HERE IS YOUR ANSWER:

$\boxed{Frequecy = \frac{1}{time \: period} }$

Frequency (given) = 8.85× ${10}^{7}$hz

time period =
$\frac{1}{8.85 \times {10}^{7}}$

= 0.112 × ${10}^{-7}$

= 1.12 × ${10}^{-8}$
