Question

1. what is the best estimate of the frequency of the wave shown below? wave speed: 335.0 cm/s 0.40 hz 0.85 hz 1.25 hz 2.50 hz

Explanation:

Step1: Determine the wavelength

By observing the graph, the wavelength $\lambda$ is approximately 400 cm.

Step2: Use the wave - speed formula

The wave - speed formula is $v = f\lambda$, where $v$ is the wave speed, $f$ is the frequency, and $\lambda$ is the wavelength. We know $v = 335.0$ cm/s and $\lambda=400$ cm. Rearranging for $f$, we get $f=\frac{v}{\lambda}$.

Step3: Calculate the frequency

Substitute the values into the formula: $f=\frac{335.0}{400}=0.8375\approx0.85$ Hz.

Answer:

0.85 Hz
