what is the speed of a wave with a wavelength of 3 m and a frequency of .1 hz? 0.03 m/s 0.3 m/s 3.1 m/s 30 m/s

Explanation:

Step1: Recall wave - speed formula

The formula for the speed of a wave is $v = f\lambda$, where $v$ is the speed, $f$ is the frequency, and $\lambda$ is the wavelength.

Step2: Substitute given values

Given $\lambda = 3\ m$ and $f=0.1\ Hz$. Substitute into the formula: $v=(0.1\ Hz)\times(3\ m)$.

Step3: Calculate the speed

$v = 0.3\ m/s$.

Answer:

0.3 m/s
