a wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. what is the frequency of this wave…

Explanation:

Step1: Recall wave - speed formula

The wave - speed formula is $v = f\lambda$, where $v$ is the speed of the wave, $f$ is the frequency, and $\lambda$ is the wavelength. We need to solve for $f$, so we can rewrite the formula as $f=\frac{v}{\lambda}$.

Step2: Substitute given values

Given that $v = 6\ m/s$ and $\lambda=12\ m$. Substitute these values into the formula $f=\frac{v}{\lambda}$, we get $f=\frac{6}{12}$.

Step3: Calculate the frequency

$f=\frac{6}{12}=0.5\ Hz$.

Answer:

A. 0.5 Hz
