Answer 1

To determine which wave has the lowest frequency, we can use the formula that relates wave speed (v), wavelength (λ), and frequency (f):

\[ f = \frac{v}{\lambda} \]

Given that the wave speed (vw) for all waves is 600 m/s, we can calculate the frequency for each wave using their respective wavelengths (λ):

1. **Wave L**:
- λ = 120 m
- \( f_L = \frac{600}{120} = 5 \, \text{Hz} \)

2. **Wave M**:
- λ = 150 m
- \( f_M = \frac{600}{150} = 4 \, \text{Hz} \)

3. **Wave N**:
- λ = 100 m
- \( f_N = \frac{600}{100} = 6 \, \text{Hz} \)

4. **Wave O**:
- λ = 50 m
- \( f_O = \frac{600}{50} = 12 \, \text{Hz} \)

Now, we can compare the frequencies:
- Wave L: 5 Hz
- Wave M: 4 Hz
- Wave N: 6 Hz
- Wave O: 12 Hz

The wave with the lowest frequency is **wave M** (4 Hz).

So the answer is **wave M**.
