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

Explanation:

Step1: Recall wave - speed formula

The formula for the speed of a wave 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 $f$.

Step2: Rearrange the formula for frequency

Rearranging $v = f\lambda$ gives $f=\frac{v}{\lambda}$.

Step3: Substitute values

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

Step4: Calculate the frequency

$f = 0.5\ Hz$.

Answer:

A. 0.5 Hz
