Question

question 1 of 33
a wave has a wavelength of 1.5 m and a frequency of 6.0 hz. what is the speed of the wave?
a. 7.5 m/s
b. 9.0 m/s
c. 0.3 m/s
d. 4.0 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 $\lambda=1.5\ m$ and $f = 6.0\ Hz$, we substitute into the formula: $v=6.0\ Hz\times1.5\ m$.

Step3: Calculate the speed

$v = 9.0\ m/s$.

Answer:

B. 9.0 m/s
