Question

A wave has a frequency of 336 Hz has a wavelength of .33 m. What is the velocity of the wave?
Group of answer choices

156 m/s

111 m/s

330 m/s

343 m/s

Answer 1

The velocity of a wave can be calculated using the formula:

\[
v = f \times \lambda
\]

where:
- \( v \) is the velocity of the wave,
- \( f \) is the frequency of the wave,
- \( \lambda \) is the wavelength.

Given:
- Frequency (\( f \)) = 336 Hz
- Wavelength (\( \lambda \)) = 0.33 m

Now, substitute the values into the formula:

\[
v = 336 \, \text{Hz} \times 0.33 \, \text{m}
\]

Calculating this gives:

\[
v = 110.88 \, \text{m/s}
\]

Rounding to two decimal places, the velocity of the wave is approximately 111 m/s.

So the correct answer is:

**111 m/s**
