Question

5. What is the speed of a wave that has a frequency of 600 Hz and a wavelength of 2 m?
Show the steps you used to solve this problem.

Answer 1

To find the speed of a wave, you can use the formula:

\[ \text{speed} = \text{frequency} \times \text{wavelength} \]

Where:
- Speed (v) is measured in meters per second (m/s),
- Frequency (f) is measured in hertz (Hz),
- Wavelength (λ) is measured in meters (m).

Given:
- Frequency (f) = 600 Hz
- Wavelength (λ) = 2 m

### Steps to solve:

1. **Write down the formula**:
\[
v = f \times \lambda
\]

2. **Substitute the given values into the formula**:
\[
v = 600 \, \text{Hz} \times 2 \, \text{m}
\]

3. **Calculate the wave speed**:
\[
v = 1200 \, \text{m/s}
\]

### Conclusion:
The speed of the wave is **1200 m/s**.
