To determine which wave has the lowest frequency, we can use the formula for wave frequency:

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

where:

  • \( f \) is the frequency,
  • \( v \) is the wave speed,
  • \( \lambda \) is the wavelength.

In the table, the wave speed \( v \) is constant at 600 m/s for all waves. We need to calculate the frequency for each wave:

  1. Wave L: \[ f_L = \frac{600 \text{ m/s}}{120 \text{ m}} = 5 \text{ Hz} \]

  2. Wave M: \[ f_M = \frac{600 \text{ m/s}}{150 \text{ m}} = 4 \text{ Hz} \]

  3. Wave N: \[ f_N = \frac{600 \text{ m/s}}{100 \text{ m}} = 6 \text{ Hz} \]

  4. Wave O: \[ f_O = \frac{600 \text{ m/s}}{50 \text{ m}} = 12 \text{ Hz} \]

Now we compare the frequencies:

  • \( f_L = 5 \text{ Hz} \)
  • \( f_M = 4 \text{ Hz} \)
  • \( f_N = 6 \text{ Hz} \)
  • \( f_O = 12 \text{ Hz} \)

The wave with the lowest frequency is wave M, with a frequency of 4 Hz.

So, the answer is: wave M.
