Mathematics

Step-by-step explanation:

The formula we use to solve this would be: $T=\frac{\lambda}{v}$

Where

T is the period in seconds

$\lambda$ is the wavelength in m, and

v is the speed of the wave in m/s

We have $\lambda$ equal to 100, and v = 200 m/s. Plugging these into the equation, we get the period:

$T=\frac{\lambda}{v}\\T=\frac{100}{200}\\T=0.5$

C is the right answer.
